[Q] Rooted Desire stuck between ROMs!!! HELP!!!

Hi guys, I've had my Desire rooted for around 2 months and have used loads of
ROMs/Mods etc. It's fair to say I know the procedure. At the moment though I'm
puzzled and worried because I have lost my previous ROM and can't get a new one
on!
I was flashing a new version of Pinky Desire over the previous one (without wiping)
and it never got to the reboot screen. So I took out the battery and put it back in
to reboot it. It got to the custom boot screen and no further so I then booted into
recovery and wiped data and cache and re-flashed the ROM, but the result was
the same...
So I tried this a couple more times until suddenly the recovery-windows.bat file
would no longer put me into a recovery menu. I've tried everything I can think of
(using my original Goldcard etc) but nothing is fixing it- it's like I've lost root access.
How can I make my phone useable again? PLEASE HELP!!!
EDIT: In case it makes a difference I did delete what I thought were some old .zips from my SD shortly before this.

Install an official RUU, then re-root it? I guess some of the pro's got some better answers though

Download the ClockworkMod recovery, rename it in update.zip, put it in the sd, enter recovery, when you get the red triangle press vol up+power, select to flash update.zip.

Yep, flash an ruu, then re-root, only this time use unrEVOked and for future when flashing roms use the newer recoveries like clockworkmod or amonra.
The old recoverywindows.bat file leaves you at risk of the usb brick. You may well already have that now if you pulled the battery mid flash.

Thanks all. Haven't had a chance to do this yet but will. I did manage to flash an update.zip but it won't detect the sd. will try with clockwork mod.

Tried this but all I'm getting is cannot find directory. It retries about 12 times then
reboots. Just won't work.

When trying to flash an RUU it comes up with 'Error 170: USB connection error'.
This is weird because the device's bootloader recognises that there's a usb
connection. Any ideas?
EDIT: Seems like the phone in it's current state simply can't mount an sd card.
Gotta try some alternative methods for getting the RUU to run...

Had almost same problem.
I even couldn't flash update.zip
the problem was in SD. it was working OK in windows, but phone couldn't mount it. soved problem with reformating using SDFormater, when formated with clockworkmod.

I've two SDs and neither is working though so...

two things
the windows unlockerthing.bat was only supposed to be run one time, after that you could access the menu pressing vol up and power...
Why would you pull the batt on a Flash??

Pulled the battery because the device said flash completed but didn't do anything for over 5 mins. Won't make that mistake again. I've actually bricked the USB so this thread is a little pointless now
Oh and I did fix the SD issue

[Q] Can't mount USB Mass Storage onto my PC as ICS has crashed on my Kindle Fire

I rooted my Kindle Fire using KFU 0.9.5 and flashed a custom ROM. It worked fine for a few days and then just crashed -- The options bar located on the bottom disappeared and the error message was: System UI has crashed. (I have attached two pictures for better clarity)
Also, whenever I boot up, there is no yellow flame that appears, it goes to the moving colourful discs straight on.
I tried using terminal emulator and entered many codes in some hope of mounting USB Mass Storage so that I can use KFU and restore my Kindle, but in vain.
I have tried EVERYTHING. I've been at this for 6 days now and am at wits end. :crying: I have read up close to a 100 articles; this was my last resort.
I just want to get the Kindle's stock OS back - no root, nothing.
And the only was is, I suppose, if I am able to mount my Kindle as USB Mass Storage onto my computer.
ANY help is appreciated!
AndroBoss.

As it now runs on ICS, there is no Gingerbread for Kindle anymore on it. I can't wipe it clean from the device or atleast I don't know how to, please help?

All the wipes you should need to perform can be done in twrp recovery. Wipe factory reset , wipe cache , wipe dalvik and wipe the system. Reflash ROM , reflash gapps , reboot then system if prompted and you should be good to go.
Edit: failing to use the correct method to return to stock will just cause more problems. Rather than trying to go back to pure stock without fff and twrp I suggest you perform the above wipes and flash this instead http://forum.xda-developers.com/showthread.php?t=1439916 its just modified stock with Google play and it will not wipe out your recovery and bootloader.

Okay, I will flash what you suggested but that's the problem. I am unable to access TWRP recovery from my Kindle. When it boots up there is no yellow flame that appears as the custom ROM is ICS 4.0.
I tried mounting a twrp.img on to the SD Card after downloading one straight onto the tab but of no avail :/
What do you suggest? Is there any way I can get the TWRP Recovery to come up so that I can get the modified stock that you suggested?
Thanks for your help, regardless

I know you said you read "close to a 100 articles" in your OP, but I suggest you do a little more reading. Get yourself acquainted with the key software components of the Kindle Fire and how they work together. Some of the things you say in your posts suggest you would benefit from the first post here...
http://forum.xda-developers.com/showthread.php?t=1552547
- The yellow flame you are looking for is an older version of the FireFireFire (FFF) bootloader, but there is a newer/better version.
- The KF cannot go to "the moving colorful discs straight on" because the first thing you will see is the bootloader's bootlogo.
- You must determine what bootloader is currently installed on the device because it is key in determining how you can get into recovery (TWRP).
- "Mounting" sdcard means to make the storage space available to either the host computer or the Kindle Fire, but it almost always means the former. Your comment about having "tried mounting a twrp.img on to the SD Card" doesn't make sense.
My guess is you do not have FFF installed and the device is booting with the stock bootloader. Odds are you will still be able to boot into your current ICS system and execute an adb command to set the bootmode to recovery (5001). Then a reboot should take you into TWRP. At that point, you should try to mount the sdcard partition onto your computer and transfer the latest FFF and whatever ROM you want to flash. Be sure to install FFF as soon as possible. This will allow you to get back into TWRP even if your system software becomes unbootable. Only when you are comfortable with FFF and TWRP should you consider flashing another ROM onto the device.
In broad strokes, the above paragraph contains the steps you will take to get your device running properly again. If any part of it doesn't make much sense to you, I suggest you read the above article again. Then, you can figure out the specifics commands from the third post of the link above and the following...

[Q] phone crashed last night, now says it needs to be activated, wont activate

Hoping someone here can give me some help. Sometime last night my phone crashed - had an error message on the screen asking me if i wanted to restart - basically the android version of a blue screen.
I rebooted and when it started up it tried to activate but failed. Tried it a few times, never activated. I called sprint and they had me type in 2 different codes:
##72786# which didn't get an error but didn't help anything
They had me try a 2nd 6 digit number, which I'm not sure if it's unique to my phone or not so I wont post it here but that did nothing at all - typed in the ##______# and nothing happened. They claimed it was because the phone is rooted, but the phone is ONLY rooted. I haven't installed a new OS it's the stock rom as far as i can tell.
Anyone have any ideas whats going wrong here or how to fix it?
thanks
edit: and apparently now I wiped the OS from the phone since it wont go past the LG logo. Is there some way for me to either copy a rom onto the phone from TWRP or copy a backup onto the phone? I've got a couple of TWRP backups saved on my pc, but since the phone wont start up I don't have any way of copying them onto the phone - damn non-user removable sd cards.

Can you boot to recovery?
If you can, then flash a newer TWRP build, they have MTP support, you can mount it while connected to your PC, copy a ROM zip over (there is a stock on in these threads somewhere), flash it from recovery, wipe everything first. Then you should be able to boot into a working device.

Yes I can boot into twrp, but I'm not sure how to copy files that way. I tried using adb but it couldnt find the phone. Can you give me some tips on how to copy a new ROM or twrp backup to the phone?
Thanks

Yes, first thing is to flash this.
http://cubegamemc.de/kevinjoa/lollipop/recovery-geehrc/twrp/
You can flash it through fastboot.
follow these steps:
1. Download and place the file on your PC.
2. Reboot your device into Fastboot Mode. To do that, simply hold down the Volume DOWN+Power buttons together.
3. Once inside the Fastboot mode, connect your device to your PC via USB cable.
4. Launch a Command Prompt Window in the folder you saved the recovery image to. You can do that by holding down the Shift button on your keyboard and right-click on any blank area on the screen, then select Open command window here.
4. Enter the following command into the Command Prompt Window. You need to replace recoveryfilename.img with the actual name of the Recovery Image you downloaded.
Code:
fastboot flash recovery recoveryfilename.img
5. Once it is done, reboot your device
Code:
adb reboot recovery
should do it. If not, just hold down the power button, and get back to recovery.
at that point you should have the newest recovery. This recovery has MTP enabled so you can transfer files just like you can if you had a running device.
Once it shows up on you PC you can transfer a ROM zip or a backup to the internal SD. From there you I am sure you know how to flash a zip or restore a backup. It is the same as an older version. MTP should be under the "MOUNT" section of TWRP. I don't remember because I have a different device now.
Good luck!
If this doesn't work, follow the thread here: You would need the super big full bin file if you do though because you do not have a working ROM or zip currently on your internal SD card and this contains a very old recovery, but it does work.

http://theunlockr.com/2013/03/26/how-to-install-twrp-recovery-on-the-lg-optimus-g-att/

My phone seems to behave a little differently than what you describe. Holding down the volume down and power button just turns it on. Holding vol up and power puts me into a screen with the android bot on it with the option to restart bootloader, go into recovery, or power off. and at the bottom there's some text indicating fastboot mode is on.
I was able to use the fastboot command to load the newer recovery. But for some reason, none of the adb commands work on my phone.
I'm copying a twrp backup to the phone now and i'll restore that. Hopefully that'll fix the issue of the phone not booting and if i am really lucky, fix the issue of the phone not being activated, but I'm not too hopeful about that.
Thanks again for all your help

hey - just wanted to say thank. Got my phone to boot back up again. Unfortunately the backup restore doesnt seem to have fixed my initial problem. Phone is back to saying it needs to be activated. Any ideas about that? It's also showing zero bars - not sure if that's what it's supposed to show when it's not activated.

EDIT:: TRY THIS FIRST<
Do a full wipe of the system and data, not internal. GO to recovery, select wipe, then factory reset. Then boot your phone. You will have to setup everything again but it might help. If it does not, you can always restore your backup again.
^^^^^^^^^^^^^^^^^^^^^^^
Interesting that your phone was the opposite for the buttons. Maybe I had it backwards, or maybe my source did. Either way I am glad you have a device that boots now.
Check this...
Go to the about section and see if your imei and other information are blank or have 0's. I am almost certain that there are 0000's.
If that's the case then you lost your EFS some how. and there is a way to recover that as long as you have a backup somewhere. You should have one somewhere if you used freegee to unlock your phone in the beginning. If not, perhaps an earlier backup you had of your device. A lot of the recoveries for this device make a backup of the EFS.

well i just dropped the phone off at a sprint repair store to see if they could do anything with it now that it actually boots. If they can't fix it, I'll try what you suggested. Although i already tried a factory reset and that didn't help.

well you are right about the esn/meid/IMEI - they are all zeros
I did a restore and then used freegee to restore the efs. Will free tell you if there is no backup of the EFS? Because i restored it, it finished pretty much instantly, and then i restarted the phone just be safe. Unfortunately it didn't fix it.
Phone still says searching for service, and now there's a little red x over the bars. Before the bars were blank but there was no red x. Not sure if that makes any difference.
Also, something else weird is going on now. I just tried copying a newer backup to the phone to try and restore the newer one. I don't seem to be able to copy files now. When i drag the folder windows , it says the device has stopped responding. If i try and copy each individual file in the backup folder, it starts to copy, and then just sits there like it froze, or like it's copying so slowly it might as well be frozen. I had to reflash twrp to the newer version and then I'm able to copy files.
Reloaded the efs backup again but still can't activate/have all zeros.

i747m boot loop, download mode only - data recoverable?

So, a little background. Full stock recovery, latest Telus 4.4.2 firmware.
Phone may have suffered a drop and/or some water damage during an episode of blackout drunkenness. Yes, I know, I'm an idiot.
Worked fine for a day or two, then began randomly shutting off, seemingly at times when the phone's CPU was under stress. Keeping it in airplane mode seemed to help avoid the reboots somewhat but not completely.
This began right before I was leaving for vacation, and had no time to go replace it. Then, after successfully taking a bunch of awesome pictures while on vacation, the phone decides to go into a boot loop. Can only boot into download mode.
I've got another phone now, but would REALLY like to get the data off the phone if at all possible. I'm assuming there must be some hardware issue at this point causing the boot loop, so I'm guessing that restoring the phone to 100% original working order is probably out of the question.
Any suggestions? I'm guessing something got corrupted, but I'm wondering if maybe I can flash a new recovery or re flash the stock rom via odin and hope it boots up long enough to get the data off? Will it wipe all my data if i try to flash via Odin? Should I take it in for a JTAG? are there other options like getting someone to dump the data off the memory chip somehow?
Thanks in advance.

Since the phone will enter download mode, I suggest flashing twrp 2.87 onto the phone, boot into recovery, mount the data partition, connect the phone to a computer, and try to copy the data to the computer.

Okay, where is a reputable source to download Odin, and what version should I use?
Also, can you provide a link to the exact instructions for flashing TWRP? I looked at the info available on their website and it's not that clear...
And so once I've booted into recovery and mounted the data partition, I leave the phone on, correct? Dont do anything, just connect it to the PC, and it should show up there?
Thanks so much for your help

Okay, I was able to flash TWRP successfully and boot into it.
However, when I attempt to mount the data partition, it won't let me. When I go into the log files, it says unable to mount /data, unable to mount /system, unable to mount /cache, etc......
Also says Internal Storage 0mb ....
So.... i'm guessing this is really not good
Any further suggestions??

If it can't mount the partition and the size is 0, looks like the internal memory is shot.
The only other thing you could try would be to re-flash the stock ROM without wiping anything to see if it will boot. If it fails to flash via Odin, I don't there is much you can do.

Nexus stuck in boot loop - unrooted - Backing up photos from bootloader or recovery

Hi.
Apologies if this is a very naive question, I am not particularly familiar with mods, roms and so forth.
I have rooted another phone in the past, but that is all.
The situation:
- Samsung Galaxy Nexus
- Not rooted/unlocked. Stock android automatically updated to the latest Android version supported
- Android developer option NOT set in settings
- Stuck in a boot loop: boots to android and then after a few seconds reboots, so no time to do anything
- Not sure how it happened, I had it for years, it was in my pocket and suddenly started doing that.
- Android fastboot and recovery loads up no problem
- I have tried anything I could find online to fix it: deleted cache, rebooted in safe mode, removed battery for 10 hours
- Nothing seems to fix it, it keeps rebooting
- I want to try a factory reset, but my family photos are in the phone
- Google synch seems to have stopped functioning for this device a year ago, all my 2016-17 photos and videos are locked in the phone.
Admitting there is nothing to do about the loop problem:
Is there any way I can copy photos and videos via usb while in recovery mode?
After I will reset the phone via recovery menu, hoping it will fix it. IF that does not fix it, I will flash another rom in. But I really do not want to wipe my data before backing them up.
I am assuming the answer is no, you cannot access the internal memory in fastboot/recovery unless your phone is rooted.
But I would like an expert opinion before I resolve to wipe one year of photos and videos which I will regret losing.

@mcaldo DON'T DO FACTORY RESET, EVERYTHING WILL BE LOST
which recovery are you using..?
if it's TWRP, then it's easy..
- boot into TWRP recovery
- go to "Mount" tab
- find "enable/disable MTP" button at lower options.. (enable it )
then connect your phone to that PC, where you always connected in past, ( to eliminate driver installation stage, all drivers will be preinstalled )
Regards

By recovery, I meant 'android system recovery'
It gives me the following options:
reboot system now
apply update from ADB
apply update from USB drive
wipe data/factory reset
wipe cache partition
Is any of the above useful?
Unfortunately, I do not have any alternative recovery software available
Edit: Googling I found this: "Apply update from ADB: The Android Debug Bridge allows you to plug your device into your PC and issue commands from there. "
If I can issue commands through ADB, perhaps there is a command to copy data from my phone to my computer?

Yes, you can copy through adb commands..
Get and extract Minimal ADB and Fastboot from here: https://forum.xda-developers.com/showthread.php?t=2317790
From PC, run CMD to extracted folder directory.
Connect phone to PC, go to update from ADB(in recovery),
Type "adb device" , it will show serial number and connected..
Then "adb pull /sdcard " (if you know particular directory of data then write it like /sdcard/photos,, otherwise writing /sdcard will copy all folders from your phone. )
it will start copying to same adb folder ..

Thanks for the advice.
I followed the instructions closely, and nearly got there.
adb devices returns
#serialnumber sideload
so all good
but adb pull /sdcard returns
adb: error connect failed: closed
I tried several other commands with no success
kill-server and start-server work fine but do not solve the problem
adb usb returns
error closed
So, I am starting thinking that the problem is in the bootloader being locked.
However, if I unlock it, it will be wipe all my data, I understand?
Googling about it, I found this:
The behavior is status-by-design. Your stock recovery is not designed to grant shell access. Your only choice here is to somehow manage to flash a custom recovery. – Firelord Dec 30 '15 at 14:19

To achieve something similar to what @FireLord suggested: TWRP can be booted on many devices without being installed. For that, find a matching image, then boot to the bootloader and run fastboot boot twrp.img. Btw: you can check with fastboot devices resp. adb devices whether a device is visible to the corresponding tool. – Izzy♦ Jul 8 '16 at 19:40
So I understand one could boot TWRP without installing it, but I am not sure if that means I could do that with the bootloader locked?
I found WugFresh nexus root toolkit which seems to do that, among many other things, but again it warns that the phone must be unlocked (using the android build "Android *.* Any", I did not know what else to choose, not sure if that makes any difference as for locked/unlocked requirements)
EDIT: my fastboot screen reads "FASTBOOT STATUS - Failbootloader locked" as the last line, when trying to run TWRP without installing.

Yes, unlocking bootloader will wipe everything..
What actually you did ? Why it went into bootloop ???
I have also read that about boot into TWRP without installing.. and it worked for many one without unlocking bootloader... Don't know why not on GNex.

A very good question, to which I have no answer, unfortunately.
The phone was used by my wife for 2 years and then by me for other 2. I recently changed the battery.
Never rooted or unlocked. No unusual apps installed. I am a very basic user, as you might have guessed, and being my only phone at the moment, I really would not risk experimenting with it.
It went very slow over the last 4 months, so I was planning to reset it.
I put in my coat pocket for a few hours, when I took it out it had a train ticked stuck to the screen and was quite warm and on the lock screen. It froze, so I took the battery out and restarted it. From then on it is stuck in a loop, not sure why really.

It seems there might be a problem with the fastboot drivers on my computer, even selecting them from device manager did not work. Win7 refuses to install. The ADB drivers in theory work fine though.

If you have done nothing modification to system, then wiping data should work, but i have doubt if it also wipes personal data too, on TWRP it wipes data excepting /data/media/ which contains all personal data.. but don't know about wiping on stock recovery...
I hope you will find solution as soon as possible..
Regards.
PS. I can install stock recovery and try wiping /data.. and check what things get wiped.. but i need little time for that experiment...

Thanks so much.
Looking at google's documentation on the nexus:
You can remove data from your Pixel phone or Nexus device by resetting it to factory settings. Resetting to factory settings is also known as formatting the device or doing a "hard reset".
If you're factory resetting your device to fix an issue, make sure that you've tried all other troubleshooting options first. Find out how to troubleshoot your issue.
Important: Performing a factory reset will erase all data from the device.

It would seem that indeed all data will be removed.
This point, I will research a bit more into drivers, in case that is what it's preventing adb pull from working.
I really need a working phone, so if that fails I will hard reset, then unlock, root, flash in an alternative bootloader and perhaps a rom, and put ubuntu touch in dual boot. That will hopefully prevent me from loosing data in the future.
Sorry, this is out of topic to my question, but, , could you suggest any stable, solid rom for the nexus?
I read good things of CM12, and I ran into one which seemed to do to quite well with split windows, but I do not remember the name right now.
EDIT: I remember the name of the rom now, it's https://omnirom.org/about/

A last question if you can..
I tried to solve my boot loop problem by sideloading an update from google (maguro yakju yakju-jwr66y-factory-4cadea65.zip)
It loaded it fine but then failed because the installation it says it is not signed.
Basically, being a stock bootloader recovery from Samsung, it will only sideload OTAs from samsung, not the stock ones from google..
I cannot find the samsung ones anywhere, not for the nexus anyway, just the newer devices..
By any chance do you know where I could download proper Samsung OTA zip updates for the nexus?

Well, I talked with an android developer who confirmed that, unless you have a friend working in criminal forensic technology or similar, there is no way to get around a lock on this phone to pull data out.
So, sadly, I have wiped my phone by unlocking it, flashed TWRP and then omnirom with gapps.
My photos are gone, including a bunch of stuff my kid had made and asked me to photograph for safeeping. Very safe indeed
He kept asking me why they make the lock like that, instead of allowing some kind of password, perhaps he has a point.
So, it is quite unlikely that somebody who knows as little as I did will ever read this *before* finding themselves in the same situation.
But if you do, back up your data, unlock and flash TWRP, clockworks or some alternative, and thank yourself if and when disaster strikes..

@mcaldo wiping data/factory reset in STOCK RECOvERY will wipe everything... There is very few chances to get backup...
And yeah i found something interesting..
You can flash system.img.. only system files will be corrected not anything else..
Get appropriate zip from here : https://developers.google.com/android/images
Now take system.img to ADB/Fastboot folder ( i assume you know how it works )
Just go "Fastboot flash system system.img"
It will rewrite system partition..
Another one:
See downloads on this thread..
One says NON-WIPE, if you want me to try that zip, i will again require time for that. See here : https://forum.xda-developers.com/galaxy-nexus/general/guide-restore-to-stock-unbrick-galaxy-t2065470
