[Q] Boot loop - download/recovery mode accessable - General Questions and Answers

I feel like such a noob...
I couldn't find a thread that addresses my specific problem...
My Captivate i896 wont start up any OS. When booting it displays:
i896 and samsung
i have access to Recovery and Download mode... however Odin and one-click unbrick cant recognize the device unless its in Recovery mode.. but after it recognizes.. it fails to contact my device.
wile in recovery mode i deleted user data, cleared cache data, and formated sd-card... im not sure if that was a good idea?
what can i do to get my phone back into stock?

now i dont have a captivate, so i dont know what odin is
about going back to stock, i wouldnt worry about that until AFTER you get a working os so id copy a custom rom onto your sd card and flash it in recovery

So, I made the noob mistake of placing a new ROM and radio on my phone, formatting my cache, dalvik, and system, then installing the radio first. This caused my phone to fail to boot for lack of an OS, and when I went into bootloader, it attempted to update the radio.
So here is what I learned. If you somehow cleared your OS, you need to re-install or install a new OS. If you have access to recovery, you should be able to do this. While I am not entirely familiar with ODIN, I imagine it allows you to mount the phone as a storage device? From there, simply place the ROM on your phone and flash.
If this doesnt work, then I can't imagine what you will need to do. I have a friend with ODIN, and will play with it a little to attempt to get a little more familiar with the program in an attempt to help you out.

Nexus S won't boot to OS

I have the Nexus S from Telus.
It was rooted, unlocked, running CM7. However I've been having issues with it freezing and decided I want to go back to the stock rom.
I ended up downloading what I thought was stock ROM for my phone (Stock GRH78 Nandroid Backup in this Tutorial http://forum.xda-developers.com/showthread.php?t=884093) however after it flashed my phone, I ended up with a phone which was essentially stuck in Airplane mode, would not connect to Telus. I'm guessing that it has the wrong radio for my phone/carrier?
So then I ended up finding a zip file someone posted Stock-GRJ22-i9020A-unsigned which should have worked, I ended up flashing the zip file from recovery.
It said it installed fine. Rebooted, and now the phone just cycles the Samsung Loading screen endlessly.
I tried to go back to recovery, and it gives me yellow triangle with !.
Is there any way to flash the recovery image back to the phone?
I plug the phone in and the PC won't recognize a device.
I installed the Android SDK
Ran the command adb devices, no devices attached to the PC.
I tried fastboot devices - blank
I don't know how I'll be able to get files back onto the phone SD Card for flashing etc...
I had the exact problem two days ago...flashed an image that jacked my phone up. Wouldn't boot past the google logo. Sat there indefinitely.
Read this thread and see if you can get it work. In a nutshell, you need the PDA net drivers installed. Since PDA net can't install the app on your phone (because it's not booted into an OS) leave the install program in limbo and voila, fast boot will work. From there, push the recovery.img (google Clockworkmod recovery image), boot into recovery and you are off to the races.
This is, of course, assuming you already have a ROM image on your internal SD card you can flash to get back up and running. I'm not sure how to install a .zip image ROM if you can't gain access to your SD card.

Good luck, I know the feeling. It blows.
Ah, just found out how to install a file on a phone that won't boot.
You do need to flash CWM recovery first though.

Good news! I tried a factory reset/data wipe and rebooted the phone.
It doesn't hang anymore, all functions restored and the phone is working on Telus again!
I guess I had to format data, clear cache, before the flash of the rom.
So relieved.
Issue has been solved!

Bootloop help

So I was cruising around the Nexus S forums and found a rom I liked after I unlocked and rooted my phone.
I flashed Paranoid Android and then flashed the Matr1x kernel. Thus putting me in a neverending bootloop.
No ability to go back to CWM so I can't restore. And I can't put it in download mode so no ODIN.
What the heck do I do?
Can anyone help?
BTW if this is actually called a soft brick I'm sorry my terminology might be off.
Also I did this because the last phone I did extensive flashing with was an HTC Inspire 4G and it was easy to flash stuff just clear everything and flash what you wanted no bootloops. Sadly this phone not so much.
Hmm... No recovery...I've been stuck in a bootloop but I had recovery!
Sorry for the useless post, I cant help you..
Are you able to get into bootloader?
Usually when a bootloop occurs you should still be able to go in recovery.
When you say "no ability to access CWM" do you mean ROM Manager? Or the recovery mode?
What happens when you try to access the recovery mode?
same issue like urs
http://forum.xda-developers.com/showthread.php?t=1775933
try clean install;
flash Rom-Wiper.zip
flash Dalvik-Wiper.zip
then;
factory reset,
Format the system, data, cache, boot & partitions of your device.
I mean no access to recovery. CWM is Clock Work Mod Recovery. I have no access to fastboot either. The only thing my phone can do is bootloop.
You have to be mistaken.
Press power and volume up to get into fastboot ( bootloader). Then pick recovery....
That rom or kernel will not erase recovery. If your phone is in a bootloop it is making it past the bootloader
So it appears it as if I was mistaken. I got into fastboot and booted into CWM I'm still confused as to what I did, but I think I corrupted the Kernel.
It was the weirdest thing though. I tried it at least a dozen times, then I tried to run down the battery and try it again afterwards, and it didn't work so I gave up. Then I tried it again about 5 minutes ago and it worked. I'm sorry I cause you guys so much confusion. I've been doing this for so long I guess I just didn't doubt I was doing it right.

Stuck at Logo

Hello guys,
I have a problem, I hope you can help me with.
I used to have an EOS ROM. I decided to do factory reset and thats when my problems started. It didn't boot up anymore. After entering recovery I noticed it couldn't mount System partition. I tried reinstalling the ROM, but no success. Everytime I entered recovery, the System checkbox wasnt marked. So I decided to go back to stock, using http://androidforums.com/threads/return-your-xoom-to-stock.653230/. Now it is stuck at Logo screen and can't enter Recovery. (Goes to Reading ODM fuse, but not any further). I can still enter Fastboot and my laptop detects the tablet, when hooked up to it.
Please help me push the Recovery, cuz I'm getting "device not found" from ADB. I'm kinda lost here... Any help would be appreciated!
Update
I managed to install TWRP, but still can't mount System Partition. On wipe I get "Failed"when trying to clean the system part. I have tried Clockwork, it didn't help either.
Cmon guys! I don't want to JTAG it yet.

I am not very knowledgable about flashing, but one suggestion has come to my mind: if you can now get into TWRP (it wasn't clear whether you could based on your last post), try flashing a ROM without trying to clean the system partition. Just make sure the ROM matches the TWRP (i.e., big part ROM with big part TWRP).
Oh - another thought - folks in a number of threads have stated you need to explicitly follow both the recovery and ROM instructions for the XOOM. If you miss a step, people have had issues.

I ENABLED some stuff in package disabler pro, and its stuck on a non reflashable loop

I was using package disabler pro to disable some Samsung apps, like galaxy apps, billing etc. I have had the phone like this for months without problem. Today I re enabled galaxy apps and rebooted phone and now my phone is boot-looping, stuck on samsung logo. I re flashed the EXACT same rom that is on there via ODIN, (XSA g920i) and it STILL boot loops. Normally this fixes problems like this. The phone is stock, uprooted. Don't tell me I have to factory reset it all?
Will not even boot up in safe mode.
This can be moved to the Q and A section but I also didn't realise you can soft brick your phone without root.
I am definitely sure it was re enabling some apps in package disabler pro that did it. Is there some way to ABD console re enable all apps or undo whatever the program has done?
I'm willing to install twrp recovery on the phone so I can mount system and undo whatever the program has done. Does anyone know what to alter?
$10 paypal for solution that doesn't involve loosing data.
If I factory reset, will I be able to recover the files on there like pictures and images with a program?
Install custom recovery, then mount you sd partition in recovery and connect to pc then move all your pics etc to pc, then factory reset

Yea Im aware I would be able to do that but I want to be able to undo the programs influence so I can boot into my phone again.
So I take it I use the latest twrp and just flash via odin? I dont need to also flash a custom kernel?
Yeah just flash recovery with odin, you could probably try using the file manager in recovery to delete the galaxy apps apk, or fixing permissions may work, or possibly wipe cache and dalvik and may be able to boot, the custom recovery gives you a few options
I contacted the dev and he said there is a way to fix it via ABD. The stock s6 mm recovery has an ABD option, is this the same as a proper abd when the phone is booted up, or does it only allow you to push signed files and updates accross?
So does this mean it is possible to fix the issue without flashing custom recovery?
Is there another section this can be moved to? Im surpised there isnt more information for such a popular app with a common problem.
I just realised I have reactivation lock enabled. Does this mean I CANNOT flash custom recovery? If thats the case I dont even want to try.
How to enable 'Android system' back?

Stuck in Bootloop | TWRP installed

Hi, i just got my old 5 year old (now retired) device to bootup because someone had made a kernel for the device which supports overclocking so for the fun I wanted to try it
but there was one weird problem, it seemed that though the root permissions from years ago remained just like they were but magisk manager itself had lost root permissions though I was still able to grant root permissions to other applications normally
I was on an unofficial Lineage OS build and thought of returning to original Miui for the device, got the fastboot rom, got Mi flash, flashed it, booted up
but there was a catch, it would always throw an error on the login Miui account screen at startup saying "Couldn't check device security, please try again"
I had tried everything possible including:
adding a Xiaomi account
skipping sign in
Inserting a sim
None of them seemed to do anything so i flashed twrp recovery again as using mi flash to flash ur device's stock rom gets rid of custom recovery
Now here is the mistake I made
**I wiped the device clean using TWRP**
now i tried going into adb sideload mode, no matter what I did my PC wouldn't detect my device, tried going into fastboot mode and still my PC wouldn't recognise the device and same goes for Mi flash tool
additionally the device would automatically exit out of fastboot mode within 2 minutes and go on to the power off screen
I do have charge on the device it says it's at 87% on the TWRP menu
I can no longer bootup, im stuck at the MI logo on bootup
Device: Mi Max 2
Additional notes: I am not in a hurry as that is not my primary device so it is okay if you want to take your time to reply, even if there's no way i can get my phone to see the light of day again it's alright as the phone was retired and sitting collecting dust for 2 years now
I do not wish to visit a service center as it's not worth it for a device I'm just gonna use for a few hours then put it back into its grave again
just download that same, or another custom ROM, and flash it via TWRP (just put ROM in SD card).
Nothing is gone, i mean if you delete system via twrp of course it will bootloop as it don't have system.
And for reverting back to original stock ROM , i think it have to do something with encryption, or maybe just the fact you unlocked bootloader.
Best is to stay away from stock ROM, find some custom ROM which have similar to MIUI (stock rom) , somewhat improved, if you want to get as much stock ROM experience.

Hi, thanks for the reply, I tried using an SD card and unfortunately it wouldn't detect that too, what i found was I didn't wipe System it still shows that it's taking up some place (3597 MB)
i would be fine getting a custom rom on the device infact i have crdroid ready to be installed
could it be that the TWRP i installed (yes I downloaded the latest version and didn't flash the old one i had years ago) have some bugs? (I did install it from official TWRP website)
also note: though you see a Senior Member title below my name, im a complete and utter noob

Lol I thought I was the only proper noob here on xda but nice to meet other noobs here too .
I think Kraken-gz is right, once the older devices are OEM off-support its best to stay away from OEM servers, I lost couple of old lesser-known-brand devices to OEM mischief i'd say coz it happened twice to me when I reloaded the original ROMs and tried to connected to the net they went dead on the next bootup, I think the OEMs have something going on there to boot out the older devices so newer ones could be pushed in the market sooner than they were supposed to. Possible.
so, first, in twrp, try to completely format it, follow this to do it
Just, a note: in advanced wipe delete system, data, dalvik cache and cache.
When trying to reboot into system, make sure twrp complains that it have no system. (that way, you know you deleted it)
reboot it, again in twrp.
try to flash custom ROM, should work as it have clean memory.
If it doesnt flash, then make sure to note all log file from twrp while flashing, and post it here, in order to see, what failed in flashing. If it succeds, it should load custom rom . If custom rom dont work, try another one, maybe older, or one that you had previous time (before trying to go into stock rom) (just, to try to boot it somehow. But before trying another custom rom, if one fails, do proper wiping described above.
If that fails try to download oldest stock ROM, and flash it. Maybe newest is blocking it.
If that fails, there is something called EDL mode, when fastboot is not available (for hard brick, like this).
here is video just to give you overview how to do it
and text also
Edit:
WAIT, try to format it, without wiping system. maybe it will boot again.
If not, other solutions are not applicable, if you dont find way to detect that sd card. Only EDL remains.

Tried wiping data, cache and dalvik cache and formatting data, none seemed to help
and still no sd card being detected
Now edl mode
I would love to boot into edl mode but the thing is my device isn't being recognised by adb nor is it being recognised by fastboot commands
so that's where I'm stuck for now
