Very Strange Brick Problem

Hi guys, I've read and used the forum for years and upgraded my Cingular 8525 a ton without troubles (followed Vanx's method for vista and for upgrading), but this is the first time I'm really stuck without a clue.
I had Schaps latest OS on my phone working fine for about three days. It was charging with the USB hook up to my Computer. I pulled the USB out and the phone entered bootloader. I couldn't get it out. I tried using mtty to no avail, hard reset ect., but finally used the SD loading method to put TNT's latest on it (don't know why this worked). Here's the thing though, the phone will load fine on first load after I flash, but if I soft reset or turn the phone off and on it goes right into bootloader mode. The only way I can get it to load up again is to connect it to the computer's USB, take out the battery and then put it back in. the OS then boots up without fail.
I have read a ton and searched on the forum, and if any of you can help me understand what the hell I can do to fix my phone I would really appreciate it. I will post anymore info you guys would like, I really need your help on this one.
Thank you so much!

Hi,
I posted exactly the same problem today ! here:
http://forum.xda-developers.com/showthread.php?t=381284
It's really strange !
Dave

I've been reading everything and it appears that Schaps's new version seems to have this problem sometimes....I have the exact same problem as everyone else (mtty gives me the same results), and flashing a new rom doesn't get rid of it....I hope there is some way to fix this!
maybe I'll try flashing a new radio and see if that helps things....

I did notice that flashing Schaps 4.31 seems to include radio 1.50 and I had changed my anyway to 1.43 as I thought that was better for my area.
Not sure a radio will help. Maybe a different ROM version will ? Maybe 3.54 ?

I have flashed TNT's rom as well and it still has the problem now....I'm flashing a new radio as I type, I'm going to have to reflash the OS too, it just got stuck again as it was restarting.

Just a quick thing, I think I have solved my problem (not sure if it is permanent) by powering the phone off and on. Not resetting, just a simple power off. I spoke to a colleague who said the way it shuts down is different to soft reset (makes sense) and I haven't powered my phone off properly for a long time.
I have tried soft reset a couple of times since doing this and it hasn't gone to the bootloader screen once.
Maybe this is the simple fix.
I will keep you posted.

try to flash OFFICIAL ROM first , maybe there are few bug / missing file when error appear while flashing other ROM.
I hope it will help you both.
rgds,
ermen

Use mtty to see if yo have any bad blocks... I've had a few problems the same as yours and found I had 1 or 2 extra bad blocks, after the 2 "factory standard" bad blocks I got on my jasjam of course. hope this helps...

My fix didn't work.
Not sure what I am suppossed to see when I run "task 2a".
Has anyone had any luck fixing this ?

My phone isnt recognized by my computer anymore

Hello,
i've got a problem like the title says. Everytime i connect my phone to the computer via usb, i get the message the device wasnt recognized by the computer. i tried everything i know, another usbport. etc. i want to install a new radio, but without connecting to the computer it isnt possible, because i dont have the usb debugging active.
i hope someone has an idea what i can do. i have rcmix 6.1.0.1 installed.

Are you using Windoze?
If you are unfortunate enough to be doing so then you might need to reinstall HTC Sync program (sometimes it works better if you completely uninstall it first including manually removing any left over folders and files in the application data folder.

thanks for the quick answer.
i tried it, but it didnt help. where is this application data folder? do you mean on the computer? i found after uninstalling no more folders from htc.
and yes i use windows home premium 64bit.
got another idea? now it says also the device does not function properly. i hope that nothing on the device is broken.

yes he is talking about your computer... if in the "program files" you hasn´t anythink about HTC SYNC,, ALL IS OK...
but enssure that in the configuration panel-system-dispositive administrator you hasn´t any drive installed for your android device... if you have installed it, erase or uninstall it before re-install htc sync or the htc drivers....then you can re-install and reboot windoux...
and hey buddy!I recommend to you to consider to pass to linux, you will not have this type of mistakes... LOL
UBUNTU is great!

I'm afraid I don't know much about Windoze but memory serving appication data is a hidden folder so you will need to change it to view them and is in the Documents and Settings / [Your username] directory.
Device not function is just a default Windoze error when it can't install something, ignore it, your phone is fine.
If you have reinstalled HTC Sync, try a USB port on the opposite side of the PC. So if you trying ones next to each other on the front, try ones on the back (they use different headers on the motherboard).
If that doesn't work then I'm afraid I probably won't be of much more use, sorry.

thanks guys for your help, but although i followed your advices, except the one to switch to linux ;-), it hasnt got better yet. the problem is still exsisting and i dont know what else i can do.
anyone got an idea how to install radio without having usb debugging and the drivers from the computer?

Hi!
I've got the same problem with 2 different PCs, one with Win7 64-bit, the other with Win XP PRO.
Other devices work fine with the same USB ports, so i doubt it's windows or the PC...

you can´t flash any radio if your phone is not recognized
well.. Let's continue with the problem in question...
1.At some time could you have connected it?with the stock rom maybe?
2.have you tried to swich on mass storage usb mode?what´s the result?
3.when you tries to swich the phone for flash some radio you enables "usb debug"
and "only chargue"?
its a weird problem

Hey man, I've had the same problem with my old Desire (normal). Which was actually broken.. Went back to the store twice and it was sent to htc twice. But that one wasn't rooted tho. But in the end, the sensors were broken & something inside the phone that didn't recon the pc. But also try a full wipe, which helped temporarily for me.

1. yes i functioned, not only with stock rom, but also with the next few custom roms. but then 2 weeks ago the problem occured and i dont know why. before i used custom roms for months.
2. it also doesnt recognize the mass storage anymore, i dont see the memorycard as a storage device in explorer.
3. yes i turned usb debugging on and connected charging only, i flashed radios before. but the problem with the actual is, that my signalstrength is weak and so i wanted to flash the recommended for this rom, and so i recognized there is something wrong, cause my problem here occured.
normally i sync with myphoneexplorer so i didnt realize that mass storage didnt function anymore.
and because earlier i got no problems, i think more and more, that something on the phone went wrong.
maybe it helps if i go back to stockrom and undo all changes i made, to start all over again?
again thanks mate for your effort to help me out

you´re welcome companion
i reded in a spanish forum ( www.htcmania.es ) about your problem and there´s people that had the same problem with a S.GALAXY S & desire HD...
someone was solved it fullwiping and formating (in the paragraph of mounts & storage into CWM) and flashing another ROM... then they formatted their sd card with a card reader OF THE PC... later they was formatted the sd card from the pc and the problem was disapeared successfully...
BUT if it persists i think that you should (mi suggestion) send your machine to the thecnical service....

ok, will try this today evening when i'm home. if this doesnt work i will reset it in the orginial state and send it to the technical support. i will leave a comment if i was successful, perhaps this will help others with the same problem.

[Q] Huge Problem, Getting close though! Help!

(This was the most related section to my phone, if I'm wrong please move it and don't delete it. I really need help! lol.)
K I rooted last night, flashed CM7.2
Phone: LG Thrill 4G AT&T flashed to CyanogenMod 7.2
Before you guys tell me to use the search, I have! I've been working on this for 11 hours straight now cause I can't use my phone!
1st Problem: After flashing I had no service. (Yes I used search.) Tried adding APN manually, no luck with many different methods. All the other methods possible required file transfers, which leads me to my 2nd problem.
2nd Problem: My computer will not recognize my phone to transfer files. It will charge however. I tried uninstalling drivers and reinstalling them, etc.
BUT right now I have it open! Yes! Now I just want to know the best files and things to do right now before it won't let me transfer files again. I do not know why it is suddenly reading it so I'm counting on it not being able to after I try fixing everything.
If I flash to a new ROM will I get service back? Should I just go back to stock/unroot? I'd prefer to keep it rooted if I can get my service and everything working.
Thank you guys! I know a lot of these question have been answered and I tried finding them, I really did. But I'm so close now that I can actually transfer files and I just need help! Thank you. I appreciate it.
And by the way I can't just backup because when I flashed to CM7 my original backup got deleted, or just hidden deep away somewhere??

[Q] No IMEI - no baseband - Tried almost everything

Hi everyone.
As i read on so many posts, my SGN one night just drop the signal. The day after, still with no signal, i checked that had no IMEI and unknown baseband.
I had tried so many "solutions" for this to work and still nothing.
It came (when i bought it, second handed from ebay) with slimbeam rom installed. I did nothing weird to it, just simply drop signal and lost IMEI and baseband. I flashed 4.0.4, 4.2.2 from google developers web, i changed the radio for a DOCOMO one, but still nothing.
As my english is not too good, i attached a photo that explain how is my phone actually.
Please, any help will be much appreciatted as i got $300 spend on this Galaxy Nexus.

Why would you use a docomo radio? Is it a docomo phone? Have you tried flashing any other radios?

Check to make sure the contact pins that read the sim card are not damaged.

My problem isn't with the sim card, it's with no IMEI and baseband at all. Thanks anyway.

I think i just killed it.
I was trying another "solution" i found on the web, and now the phone don't turn on.
I installed an APK from the market called GSII_REPAIR and after it says to reboot the phone, now it doesn't turn on.
I read that this app is for the galaxy S2 but appear on the search for my problem's fix.

First I would put it in odin dl mode and flash stock, that should get the phone to boot again. I understand your english isn't that good but can you explain what you have tried. Im basically wondering if you have tried to play with the nv_data.bin file in the /factory directory as this may be able to make the phone get some functionality back.
The reason for the the possible softbrick is cause the gsII repair was probably deleting and replacing the wrong files ... I would probably say that this is a corrupt EFS directory and would work on the techniques out there to repair that ... either that or you have the same problem I have where it is a hardware issue and there is no real fix possible .... One method that may work the best is to try and use QPST and manually input your IMEI into nv_data.bin file ... many possibilities I just don't know what you have tried

I try to turn it on ODIN mode, and recovery mode and doesn't turn on at all.
In the same post that i saw the app, say that i can do it manually by messing with those files (nv_data.bin) but at the end mentions a nv_data file that i havent saw on the factory folder. because of that i try with the app.

so if you can't get it into odin or bootloader you have either hard bricked your phone or the battery is dead ... usually you can still get it to trickle charge if you plug it in ... if the nv_data.bin file was not in the /factory partition then i would think in some way the EFS has been corrupted or you weren't using a file manager with root access since the file is a hidden file ... biggest thing now is getting it to boot which I can only think of flashing through the bootloader or odin but i don't know everything that is possible ... someone else would probably have to help you if you can't get into either of those

Wi-Fi suddenly disabled, phone halting, root lost

So, my phone reset itself randomly today and I noticed it was unable to turn on Wi-Fi for some reason. I uninstalled an app I've had for a long time called Power Toggles as I know it also can turn on/off the Wi-Fi (to make sure the phone and it weren't fighting) and I got the idea to check the root using Root Checker. Turns out, it failed . . . So something funny is going on.
I have not knowingly taken any type of update but every once in a while, my phone has tried to update and then said it aborted it due to suspected root. Not sure if that's what happened this time around as it happened while it was in my pocket (or at least it was working before I put it away and then later on, it basically stopped working and just seems to continuously reboot for funsies).
I tried rooting my phone using Kingoroot, an LG one click method (both script and GUI) with no luck. I've never had trouble rooting my phone, especially with one click roots before! I reinstalled LG drivers, disabled and re-enabled USB debugger, switched between MTP and PTP connections, etc. I can't seem to get it to recognize the phone. When doing one root method though, it reminded me to accept the RSA fingerprint and I realized that my phone is not asking me for the RSA fingerprint for my computer. I even tried revoking previous fingerprints and no luck there either. So I'm not sure what might be repressing that option but I'm assuming that's the "root" of my rooting issue.
Anyway, does anyone know
a) why my phone would suddenly be acting this way (I think I read someone else had similar symptoms in one of the one click root forums. Tried searching for more mentions but the website seems to be halting and letting me know the issue has been sent to administrators or something to that effect).
b) how do I solve this?
Below is what I'm running:
Android Version
5.0.1
Kernal Version:
3.4.0
Build Number:
LRX21Y
Software Version:
D85021I
Security Software Version:
MDF v1.1 Release 2
I have a TWRP backup made from quite a while ago (possibly a year ago) so i can try and utilize that but I'm not sure if that will do me any good if I can't root my phone first. I don't want to do anything out of desperation that's going to put me into more trouble down the road. At least as of now, my phone boots up correctly (even if it does seem to reset fairly regularly and has a constant battery drain from trying to turn on the wifi).
Any help you guys can give me would be greatly appreciated. Hopefully, I won't just have to buy a new phone . . . Thanks in advance!

Turns out Bluetooth no longer works either. Just thought that might be worth mentioning.

Well ok, you have that TWRP backup, how about accessing TWRP?
Can you enter recovery?
Does it display your IMEI in system settings, what does it do when you try to enable wifi?
Can you make backup of your current ROM in TWRP, then try to restore the old one, try restoring only system partition if the backup was made on same Android Lollipop 5.0.1. ?

Well, I was able to get into recovery and run an old image but it appears to have the same issue. My IMEI is fine (I did a full backup including IMEI but it had a valid IMEI before as well) so that wasn't the issue. Looking at that other thread someone posted, it looks like my phone is just screwed and this is a well known issue. It looks like people were able to fix it by replacing the motherboard, which is obviously not an option for me. If that's the case, I'm guessing this is my first and last LG phone. I've never had this kind of issue with a Samsung. In fact, I'm now back on an old S4 until I can figure out what to do. Not sure what phone to get at this point.
Natus, to answer your question, the Wi-Fi icon just kinda goes in a loop like it's trying to start it up. Opening up the Wi-Fi menu has it say it's starting up the Wi-Fi but never gets there. Unfortunately, it eats up battery fast, heats it up quickly, and eventually restarts.
I'm open to any other ideas but I'm guessing it's a hardware problem at this point. Thanks for the info, everyone! I do appreciate the help!
If you have any suggestions for a new phone, I'm all ears. Trying to stay out of a payment plan so I'm looking at the Nexus 6P but I'm wondering if there's one coming down the pipeline I might want to hold off for. I'd rather buy directly from the manufacturer than go through AT&T, given the option. Might need to start a new thread for that one though . . . Thanks!
