[Q] Stuck in System Recovery <3e>

Hello all,
I'm new to android phones (my first one) and I didn't find the answer to my question.
I wanted to update my unbranded Optimus 2X (Germany; V10C, 2.2.2) and the software under Win XP ended up with an error message and had to be closed, while updating.
When I start the LG2X now, I only get "S/W Upgrade Please wait while upgrading...".
Now I could jump into the recovery (Power + Vol. down) and after pressing the home button I got into the menu of the Recovery Utility.
I can scroll between the following options with the vol. up and down buttons:
- reboot system now
- apply sdcard: update.zip
-wipe date/factory reset
- wipe cache partition
Unfortunately I can't confirm any of those options. Nothing happens when pressing the power button. The home button hides the menu and all other softkeys are without function.
Can anyone please tell me how to do a factory reset now? I'm all new to this stuff.
The man from the support, who should collect my phone, didn't get here today, like it was announced by LG support.
Thanks in advance for any suggestions!!!
Best regards from Germany

Use that to factory reset instead.
OR
Use Smartflash to do the flash the debranded ROM, that should function fine as you have to boot into software update mode anyway.

Thanks! Smartflash did the job! I can use my P990 again.

[A] Soft bricks, blocked recovery, bootloops - RESCUE TIPS

Ok, so there are a lot of threads about soft bricks and bootloops, I have answered in a lot of threads but it seems it needs separate thread to explain how to "revive" your phone from bootloops and soft bricks.
First of all, I don't guarantee that it will work but mostly this tricks do their job.
Tricks were tested and worked on many phones, but I don't take responsibility for hard bricked phones after performing tricks from this thread.
Sometimes you need to repeat process because everything must be done with perfect timing. Also if one method won't work try another.
1. Prepare your phone to press recovery combination and while plugging phone to USB or charger, hold keys and release when samsung logo appear. Do Factory reset in recovery
2. (the best) turn on phone into download mode and don't accept terms, when phone will reboot quick hold recovery combination and release when samsung logo appear. Do Factory reset in recovery
(3). Emergency download mode (when phone wib but don't turn on screen) - take off battery for few minutes, after that time hold download combination and insert battery, wait few seconds (so normally it would boot and enter dm), accept terms by pressing volume down, connect USB and flash stock Rom
4. usefull tip - Always have backup created in CWM on phone, you never know when it will be needed. What I do is creating backup every week/two weeks, also I have stock backup. I really recomend to create backup before flashing CM while you are on stock (it will guarantee everything will 100% work if something fails), it helped me a lot of times.
(recovery combination - volume up, volume down, power, home)
(download mode - volume down, home, power / accept terms volume down, decline - volume up)
In 1 and 2 "just in case" you can flash stock Rom, when it will start to reboot after Odin finish flashing, take off battery and insert again (to stop boot process) phone should boot into recovery normally but repeat point 2 to be sure.
Also, what is importiant, ALWAYS have turned on debug mode in your usb settings, first thing you should do after flashing CM, turn on debug mode.
===================================================================================================================================================
When you are switching from CM to stock, after flashing stock you will have almost 100% chance that you will have bootloop on samsung logo. You have to factory reset before first boot. So, after flashing stock, when odin will proceed reboot your phone, unplug phone and take off battery (take off battery cover before flashing, but be careful not to drop battery while flashing via odin, it would be really really bad for your phone, hold phone and battery all the time). After inserting battery back and assemble cover, go to recovery and do factory reset.

Thank you for this ! The decline download mode agrements , press recovery combination trick worked , I managed to get to recovery ! I flashed stock rom 3 times and tried repartition with pit ...but this is the only thing that worked ! Thank you

Now I have a Idea about a Un-brick:
1. If you want to return (after a Forget a clean data/cache/dalvik) When You can downgrade with .md5 Stock ROM (or Custom)
2. If Recovery Doesn't works... You can only Download Mode (Volume Down + Home + Power) - Remember it's that's not with SIM/SD Card [Maybe that's optional if it forget but I will be recommend.]
3. Flash to Newest "ClockWorldMod"
4. After Restart - That's must be take off battery and Connect USB Cable to SGMII
5. Let's Turn On Recovery Mode with a "Samsung Logo" Before Input Battery [With a Battery it's doesn't does it Start,on Fortunately...]
6. And... Let's to clean data/cache/dalvik... And that's All of "Open source Unbrick"
What Did a get:
+ Downgrade ROM without a Additonal Box (Because that's Open source with a Easy-Root and Not Close-Source as a Self of Old Sony Ericsson Tuning - But I Like a Old Sony Ericsson's Too ... And "Sony" looks from a 2007 about a Modifications and Sony is not a blocked for Android - Fortunately... And for a Today Some users remembers about a Big Seasons Tunings from K310i or K550i [I had a Two phones... That's nice what I discovered about a ROM's Modifications... And Let's praise for Sony that's Not blocked for Androids... Thank you,Sony. ]
+ That's can be again to Upgrade eg. Cyanogenmod
And... A knowledge... Hope that's share a help.

Hi OP, you might want to add this to your thread..
so, early this week, i faced a bad bootloop situation after the software update.. Even with a normal boot (no vol+,home button and power button pressing), my phone will still be stucked at CWM recovery..
Note that my phone was working fine, only the software update caused my phone to stuck in the CWM bootloop..
So, what i did was, i updated my CWM 4.0.8.2 [ my bad, cause when i rooting my phone initially last few weeks, and i've been reading outdated threads].. So, i updated my CWM 4.0.8.2 to CWM 6.x through CWM recovery..
Then, after it rebooted, i go to download mode, connect my phone through ODIN and flashed stock rom.
Now, it is working fine like new..

DXJV9 Stock ROM stuck at stock recovery

I have international Galaxy S, GT-i9000. The problem is the middle OK button dead during stock recovery.
I use this tutorial at http://forum.xda-developers.com/showthread.php?t=1102881,
QUOTE:
Special for DXJV9:
1. Flash with re-partition using 513.pit.
2. You will see a lot of red text after the flash is done, don't panic, just do a 'wipe data/factory reset' and reboot the device when done.
3. Let the device boot all the way then turn it off.
4. Re-enter Download Mode and re-flash only the CSC file without pit and without re-partition.
5. Enjoy
At step 2, I cannot do wipe data/factory reset because of dead middle button. Seems like software error as I can enter download mode just fine. (using 3 button combo).
Is there remote ways (adb/odin) that can allow me to wipe data/factory reset straight from PC? Or is it any method to solve this problem?
Thanks in advance.

Look like I got scammed. No wonder dxjvu not working as the phone I have now is m110s.

At step 2 where you ssy you cannot do wipe data/factory reset because of dead middle button, well you don't use middle button in cwm recovery, you use the power button to select options.

It is a stock recovery not cwm as i flashed stock rom through odin. Because i wrongly assume my fake i9000 is the real one, i end up flashing dxjvu with 512 partition. With that, all my efs folder got corrupted and the imei/baseband missing. Totally my fault for not backing it up somewhere.

Run LGFlashTool2014.exe
Selections
CDMA or 3GQCT doesn't matter really
DIAG
KDZ file location
then select preferred flash mode
Normal Flash: Flash ROM without losing any data. Only use this when you need to fix system error. Beware of boot loop when flashing ROM that differ from current ROM on your phone or MOD ROM.
CSE Flash: Choose this option when you need a fresh format. All data will be gone. It's suitable for upgrading or downgrading ROM or simply use this when you need to back to Stock.
Done, enjoy!
Update:
If you get
This mode is for data backup at service center ...

Click to collapse
in recovery repeat flashing the KDZ and you will get the stock recovery this time.

Wow, thx Demetris, you are my savior just in time.
With the online upgrade the phone is always stuck in a bootloop and the old offline method just didn't work as it gave me a file extract error, although I know I've done everything correct (maybe the issue was leaving the sim and sd card inside or selecting 3GQCT?)
Btw and fyi, the CSE method is only available if CDMA is selected.
Thanks for making this fast and simple tutorial that even works ^^

Thank you for the great tutorial. I tried exact accordance with my LG-P880 to update. Unfortunately it did not work, the device starts but then remains at the LG logo, no further reaction. Restart / reset no improvements. Options in Android System recoveryy <3e> do not work. Do you have an idea how I can still save my beloved P-880?

Use CDMA and select CSE flash. After update and phone sticks at lge logo remove battery hold vol +(99% of times you need to use - but for me was +) and press power on. On stock recovery factory reset and now phone will boot

I did and the unit freezes. The figure Android is flat and shows an exclamation mark.

Thanks in advance! :highfive:

For me it worked without a factory reset, just flashing and restarting.
Forget what I said, i think I did a factory reset and wiped nv partition before I flashed the new firmware with this tutorial.
@alberteske all firmwares can be found here: http://lg-phone-firmware.com/index.php?id_mod=15
but some links are broken, after clicking on a link you have to replace the "%2F" at the end of the adress with a "/"

When I select the options in the recovery mode it freezes, no action will happen.
The MD5 number is correct.

baseband change without flashing whole kdz?
isn't a way to extract the baseband files and flash them without having to flash kdz + unlock + re-install everything...?
thanks a lot in advance Demitris!

Think here you mean:
press and hold [vol -] and [power] until you got the "android recovery figure"
then clear cache and make factory reset

Somehow my phone got to the LG logo but is in bootloop. Tryed vol+ and power. I can get to stock recovery, but how to factory reset from there?

Reboot phone
ADB sideload
Factory reset
...something like that
I think that you must see that options when enter recovery(vol- and power button),then using volume buttons select factory reset and confirm with power button. I also have bootloop after flashing kdz but after factory reset phone boot properly.
BTW i use flash kdz tutorial not that method from Demetris

Huawei P9 update to Nougat

I recently tried to update my P9 to Android 7 using a tutorial from HTC Mania which has worked for many people on that forum. The phone was branded (Movistar, Spain). After following all the steps I ended up with a de-branded phone but it was still EMUI 4.1.1 Marshmallow. It says I have HW EU but the Kernel is: C900B181 Build No: EVA-L09C432B181.* Where have I gone wrong.* I was advised to post the question here by HTC Mania (KrAzYtHeBoY). Vendor info states: Vendor and country file does not exist. Any help would be appreciated.

Vendor info states: Vendor and country file does not exist.
For the above. Did you flash the c432oeminfo.zip(spelt something like that) in recovery? If not then the custid is probably mismatching with the firmware causing a number of software related issues.

Yes. Here are the steps I followed after unlocking the bootloader and installing TWRP. It's a translation from Spanish but in think you'll get the gist.
1. we will need unlocked Bootloader, TWRP Custom Recovery and be in Android 6.0
2. Download oeminfo_c432.zip and copy the .zip to the phone's internal memory
3. Download the official Firmware C432B136 extract the "dload" folder and copy it to the microSD external memory (memory is not worth)
4. We turn off the phone and disconnect the USB cable
5. Turn on by pressing and holding "POWER" + "Volume up" when you leave the logo Huawei release "POWER" and keep "Volume up" until the logo 'TWRP-Team Win'
6. Touch "Install" and select the file "oeminfo_c432.zip" zip and slide for flashing.
7. If everything is OK and not given any error we will continue.
8. let TWRP main menu and touch in "Reboot > Power OFF" to turn off the terminal
9. With the terminal off, press all at the same time "volume up" + "Volume down" + "Power" until that is installing the firmware (and we can now release the buttons)
* we will see a screen with red letters warning, not do case and keep the keys, volume up and volume down until you see the screen "EMUI" installing the update.
10. correct once the installation will proceed to update to the C432B182
starting we will ask to do a "Factory Reset", we do "Factory Reset" and turn on the phone.
To know that CUST is the correct open Phone Dialer and mark: * #* #2846579 #* #*
should appear: Vendor: hw / Country: Eu
Note: to flashing official firmware of Huawei the BOOTLOADER will be blocked and the TWRP is lost. (go to the developer options and disable "enable OEM unlock" so that all this 100% of manufactures.
I should also say that after I had finished it did show Vendor: HW/Country: EU but after doing a factory reset the phone seemed to be bricked, being in a loop where I was asked to enter my password to decrypt the phone and it just kept saying 'Decryption unsuccessful. Eventually after trying different button press combinations I got the phone to boot. Also, what is B181, I can't find any mention of that build anywhere?. Do I need to start again from the beginning? I new to all this so thank you for your patience.

This guide is 100% safe. SInce i dont get everything fro this spanish translation i cant say if they miss something.
But above guide is 100% working!

Thanks. My phone was de-branded when used the tutorial from HTC Mania, but presumable it won't hurt to follow your recommendation from the beginning? Also fastboot states that the bootloader is unlocked but you think it may be locked from when I flashed the incorrect firmware?
