[Q] reboot loop

My g2x keeps rebooting over and over again! This happened after i mounted it to my pc. it tries to read my sd card then just reboots over and over again. I have nv flash and tried to restore old back up but still does it. can any one help im thinking i need to flash stock.

you need to do a factory reset if your nandroid backup doesn't work. if that doesn't work reflash the rom.

I already did a factory reset and wipe and tried to re install the rom. it just continues to reboot. It starts up and if quick i can get into my lock screen and access things but within seconds it reboots and continues to do that

What rom are you using?

I was on a stock rooted rom when the problem happened. so i then i did a restore. when that didnt work i reflashed the stock rom that was posted on forum. i think it has something to do with my internal memory which i cannot access. this all happened when i was trying to back up my sd card while in usb and it just got an error when i unplugged it enless reboot.

I was hoping it was something simple like undervolting with a custom rom. I wish I could help. It sounds like you tried everything I would recomend. Maybe one of the real Android techie type guys can help you. I am still learning myself.

Problems with all 4.2.2 roms!

I was running slim 4.2.1 for quite some time with no problems, i loved it. I flashed 4.2.2 and my phone got stuck in NV and my phone number would come up as 000-000-3370. On first boot everything seems to be fine except that i get an error when i try to open up the play store. On my next boot is when I would see these problems. I tried everything from dirty flashing from a working 4.2.1 rom to completely formatting everything, even my external sd, and the same thing happens. This happens with every 4.2.2 rom out there. When i reboot i get stuck on the activating screen and my phone will get stuck in NV and ruim/sim wont stick no matter what i do. i don't know what else to do. someone please help!

It isn't a rom issue it is an S 3 issue that randomly occurs when flashing ROMs. You will have to flash the stock rom and reprovision your phone. I know because it has happened to me twice and both times it was with a Touchwiz ROM. You should have backed up your IMEI just in case this happens.

my imei is backed up. but why is it only 4.2.2 roms that do this?

I was able to flash back to a 4.2.1 Rom, namely pure Google for now, with no problems. but when I flash any 4.2.2 Rom the same thing happens.

All 4.2 ROMs used to do this to me.
However.
Only also happened when I flashed miui.
Now I run liquid smooth and haven't had the problem since.

God bless the American people!

do u guys think I should Odin back to stock, then root, unlock, and try to flash 4.2.2?

Actually, there is an easier way
I have had this happen numerous times and it lef me to mess with my phone a little bit. I originally thought that setting it to CDMA/SIM and then rebooting would fix the problem, but I found a simpler solution to that. The last time I encountered the problem I simply set the phone to RUIM/SIM under mobile networks and then Turned on airplane mode for a few seconds then turned it off and I found my number under phone settings and everything. Try that and let me know how it goes.
Edit: Sorry, the term is RUIM/SIM, not CDMA/SIM. My bad.

hmmm, I'll definitely give that a shot later on tonight.

well I tried it, it works. but only temporarily. once I reboot it reverts back to how it was. any other thoughts?

anyone?

try this. i had the same problem. http://forum.xda-developers.com/showpost.php?p=35600769&postcount=2

nope, none of that works either. no matter what I do ruim/sim will not stick on a reboot on any 4.2.2 Rom. I'm really getting frustrated with this.

no one has any other solutions for me?

Does your phone display an IMEI number?
Settings->About->Status
Don't need the number, just to know if you have it there....
Also do you still have Root/Unlocked bootloader?

yes, i have an imei. i lost it once before so now its backed up, i'll never make that mistake again. it was a nightmare trying to get it back. and yes, i am rooted and unlocked.

Have you done a complete factory restore through Odin? You would lose root and unlocked bootloader, but it may be faster to restore to stock, and reroot/mod than to try to find an "easy" fix. I was having some issues the other day in between a few ROM's, but I just factory restored, and restarted from "scratch". Now I am running perfect.
You may have already tried, but on page 1 you asked if you should, and I did not see a confirmation you did so.

Had the same problem... And yes, the phone must be reprovisioned. Although sometimes you can just adjust the network settings and change it from NV. That worked for me also.

I flashed root 66 via Odin, bootloop. flashed the ma2 stock image, bootloop. then flashed the lk3 stock image with success. but still with the same results as before.

tomorrow I'll try flashing g1 and start from scratch there. what do u guys think?

well, I odin'd back to bone stock G1, rooted with rootdebugfs, flashed cwm with ez recovery, unlocked my bootloader with ez unlock, flashed liquidsmooth 4.2.2 rc2 and guess what. same ****!!!!!!!!!!!!! i'm really getting fed up with this. someone has to have a solution to this cuz this is really pissing me off.

baseband unknown :((

So i must have messed up my phone while using the all in one root unlocker and so on. Im not sure what i did, but i finally got my phone to boot, and now i get no service. Im on tmobile and it says i have no sim card. When i go into about phone it shows baseband unknown.
I really have no idea what to do. Ive never been stuck in this situation. Maybe someone more experienced can point me in the right direction?
any help would be appreciated!

so furthermore, it looks like i have no data partition anymore, i can go on my chromebrowser on the phone and browse the web but when i try to install anything it says no sdcard. I also cant move anything to the phone via windows, it just freezes even tho i can see the phone and go into the internal storage.
Im really screwed here. Ive also used the fastboot files to flash back to google stock, but for some reason continue to find everything borked.
HELP PLZ!!! ahah

Also, finding that i cant mount any partition, cache, data, anything liek that. It seems like my partitions have been messed up . Not sure how to resolve that

Well it looks like your the first one to brick the nexus 5. If your imei is missing your screwed.
P.S.A DON'T USE TOOLKITS

Might be helpful to others to explain exactly what you did to your phone.

He used a tool kit. Who knows what it did to his phone
Sent from my NEXUS 5

I realize that maybe using the toolkit may not have been a good choice but considering im already here. Constructive advice might be a little more helpful... I know that with my old verizon GS3 if i lost my imei/ similar info, i could nv flash myself and get it back in certain cases. Does a similar thing not exist for the nexus 5? Id imagine that a truly unlocked device like this one should have a method to get back from anything?

If you've flashed the stick images and it hasn't fixed it then you might be out of luck. With the n4 there is a thread on how to restore the phone with LG nv flash in download mode. I don't think the tools or files are available yet for the n5 tho

i dont know what i did, but i restored the factory image one more time, then booted to stock recovery and wiped all partitions. The phone booted and my imei and baseband are back. Working 100% now. Gonna sit out the rooting and so on for now. time to relax for a bit

So you can't fastboot flash anything? Can you fast boot flash twrp recovery from the android SDK on a PC?

That's how I fixed my N4. I flashed the factory images 3 times.

Glad it's working finally
Sent from my Nexus 7

Ya, fastboot continued to work, and iw as able to flash the factory images.At first those werent fixing anything. the final time i flashed it right before it worked again, i let the phone sit and run the boot screen for about 30 minutes before i went to stock recovery and wiped. Then it booted perfectly.
The previous times i had flashed twrp and wiped which i believe was the cause in the first place.
Thanks all its working perfect now. The device is amazing,!

Sames just happened to me, but I didnt use a toolkit, i did it all manually.
Quick flash of the factory image sorted it. :victory:
UPDATE: Flashed TWRP again....All ok this time.

You guys unlocked the bootloader first right?
Sent from my SGH-I747

This has just happened to me. I have installed the stock images 2 times now.
Is there anything you guys did differently to make it work?

My N5 decided to wipe the baseband and IMEI when I went to wipe the cache through recovery. Tried to reflash factory images 5 times and each time, when the phone boots up, hangouts, camera and gallery apps force close and I still have no network signal or IMEI/baseband.
Worst bit is all I did was wipe the cache partition, done that a million times and never had this problem
Anyone know what i can do?
I've relocked the bootloader for now but I can't call Google because my only phone is the Nexus 5 so that's out of the question.
Edit:
Managed to fix it by using a slightly different set of fastboot commands.
Here's what I did:
adb reboot bootloader
fastboot flash bootloader bootloader-hammerhead-HHZ11d.img
fastboot reboot-bootloader
fastboot flash radio radio-hammerhead-M8974A-1.0.25.0.17.img
fastboot reboot-bootloader
fastboot -w update image-hammerhead-krt16m.zip
fastboot reboot-bootloader
That worked for me

After you flash the factory image, boot into recovery and do a factory reset.

You mentioned a cache wipe. Was this in CWM or TWRP? My N5 hung trying to do a cache wipe in CWM. After rebooting the sdcard was inaccessible. The solution was to flash TWRP from fastboot, and do an advanced wipe of only the cache, and give it TIME. Like 5-10 minutes. After another reboot I had the sdcard and radio back, but some write permission issues. One more reboot and everything was ok again.

Please help, stuck in Bootloop !!

Recently I unlocked bootloader, installed twrp and succesfully rooted my device, but while I was tinkering with my device I accidentally wipe all data, partition, etc in TWRP now I guess I wiped out everything including OS !!!
How can I restore ? Do I need to flash new hammerhead image ?
Right now I'm following this tutorial
http://forum.xda-developers.com/showthread.php?t=2513701
It'll be great if anyone of you can point me right way.

You can just flash any custom rom using this
http://forum.xda-developers.com/showthread.php?t=2575150
Or
Follow the thread you posted to restore a factory image..
But restoring a factory image will unroot your device..

You have twrp so the first thing you did was make a nandroid, right? Live and learn.

Thanks for the help, I just flashed new image. Everything works good except wifi, random drops + slow speed.
I contacted google for replacement and they send me RMA form. Unrooted the phone, bootlocker locked + flag reset.

Huh? You're doing an RMA why?

Before rooting wifi problem was rarely occur now after rooting problem arise more frequently, now even after unrooting wifi is super slow sometimes not even connecting. I hate RMAing but seems like no other way.

Awesome advice. I made a nandroid of my N5 first thing after getting all my apps straight. Playing with flashing a rom in TWRP I did a manual "wipe data" which proceded to wipe out the entire SDCARD in the process including my nandroid. Sooooo.... Yes, make a nandroid but also back it up to your computer or dropbox right away.

Don't RMA it, there's nothing wrong with the hardware. All you have to do is reflash the factory image. If you didn't know what you were doing, you shouldn't have been messing around with your phone in the first place. Reflash your phone back to its factory state and next time do your homework before you start tinkering. People like you are going to cause Google to change their return policy so that returns are much more heavily scrutinized.

TWRP backups not recognized

Let me start by saying that I am not new to rooting and flashing firmware, its just been a while since I last did it. I've had a nexus 5 for a few months with sprint in the US. I continually have reception issues and dropped calls so I took the phone in to a store. Before I could do that I had to reset everything to stock. I had no trouble doing any of that. I made a complete backup of my ROM before I did all that using TWRP. I went to the store and they told me to turn off lte in order to reduce dropped calls. After the I got home I set to work re-rooting and unlocking my bootlaoder. However when I went to restore in TWRP it would not recognize the backup even though it had been made only a few hours before. I spent several hours trying to get TWRP to recognize the backup. Whenever I navigated to the directory containing the backup the directory was always empty. I even tried zipping the backup and flashing it but it did not work. Eventually I decided to cut my losses and move on. I plan on taking the phone back to sprint tomorrow because I still have horrible reception issues. I really want to avoid having to go through the whole ordeal again but I am not sure what I did wrong. The only thing I can think of is that immediately after making the backup I moved it off the device onto my laptop but did not modify it in any way. I had some experience with CWM back when I had my old HP touchpad but none with TWRP, however they don't seem that different. Any help is greatly appreciated.

Did you put your backups in the correct sub-directory?
Should be something like: TWRP/BACKUPS/87095jgjg9034/nameofyourbackup

Yes, I did. I even tried renaming the backup to "backup" and still had no luck.

Well, this is interesting. I went to Sprint today and they weren't much help but before I went there I reset everything back to stock. I made a backup yesterday and when I got home I put it on my phone and it was recognized immediately by TWRP and I was able to restore it. Not sure what I did wrong last time, if I did anything wrong at all.
