Dear people of xda,
Recenlty ive receive a FOTA update to my device which runs 4.2.2. Being stupid, i did the update although i had cwm recovery installed on my devices. Now my device keeps bootlooping into cwm without being able to do anything.
Ive read tons of threads talking about this issue but i still cant get my to boot normally.
Yingy in this thread http://forum.xda-developers.com/showthread.php?t=2563527 had the same problem but the only diffrence is my pc cant recognize my device in order to do the adb fix by thecubed.
Im plugging my G2 for the first time in this computer and that is why i think my pc is failing to install drivers. I downloaded and instellad latest driver although windows device manger shows error devices not detected and the end of the process.
In order to fix my phone i just need to make me pc recognize my phone in adb although phone was never plugged before to this pc so i think my G2 wont let it access. I tried installing universal driver such as Pdanet as offered in threat but still when i write adb devices in cmd i get device offline!
Download latest adb drviers, lates lg g2 driver, lg user support tool does not recognize plugged device as well. All me sdk manger tools are patched to latest version.
PLEASE ive tried anything possible. spend like 9 hours and still nothing. i would really appriciate your help.
Thanks.
Edit: here my problem with pdanet drivers, it asks me to allow pc usb debbuging as shown in screenshot below but icant do it since im stuck at cwm recovery!
Solved!
BOOM!! after 12 hours i FINALLY manged to solved this problem. Really simple actually lol.
If anyone come across the issue please do the following:
1. Go to clockwork recovery as always, go to install zip from sdcard, choose install zip from sideload.
2. Plug your phone to pc.
3. Run adb with lastest drivers and sdk tools.
4. At the adb folder press shift+right click and start cmd.
5. write adb devices it should show your device id like this (xxxxxxxxx sideload).
6.Download latest twrp recovery from here http://teamw.in/project/twrp2/197 and if you have open europe version G2 like me download latest version from here: http://techerrata.com/browse/twrp2/g2d802
7.put the zip file in the adb folder, do not unzip it.
8. write in cmd console adb sideload xxxx.zip (xxxx is the name of twrp file).
9. cwm will flash twrp recovery over cwm.
10. reboot in recovery in advanced options.
11. now you have twrp recovery.
12. follow this guide : http://forum.xda-developers.com/showthread.php?t=2451696&nocache=1
13. THATS IT!!!
finally after going through this mess, im never using cwm recovery again. twrp is the best
good luck everyone!
Hello. Sorry for my english. I want flash my phone via rootjoy to Arcatarc's MIUmIZERO and i only can see miui logo. next i want back to stock rom from needrom via sp flash tool, i followed instructions and i stop, when red status back not change for 20 minutes. and i can't charge my phone, can't conected to pc, can't turn on, looks like dead. How unbrick my phone? please help
problem solved
how did you solve it? please let me know as i am in the same boat
If it's stuck on the MIUI screen then it's possible the bootloader wasn't flashed properly.
If you can reboot the phone in fastboot you can flash the bootloader via PC.
it is dead . the phone wont turn on . the pc wont recognise it anymore , it was fine ... untill i tried to flash stock through sp flash tool .
i was running antarcts emui,.... tried flashing using the method on umi digi forum : http://umidigi.com/forums/topic/how-to-restore-rom-version-3-03-2/ ... preloader was unticked, and when i tried firmware uopgrade option...nothing happened, and the phone was dead after that.

I managed to make it boot.
The problem is I have twrp and some chinese recovery . And I cant go back to stock.
Fastboot cant flash recovery for some reason ... so I can go back to rootjoy.
use adb side load an try to flash a working rom, the original one from umi website or emui.
can you get in recovery mode? volume (+ or - try both) and power button for some seconds
if yes go adb side load, (check google) and transfer an original rom, then flash it again in the recovery
My Umi Zero is bricked, because I cannot mount /system. I can get into the TWRP, but I cannot do anything, even restore my backup because of this. Does anyone have idea what to do?

If the system is unstable with popups etc or with damaged partitions you can get past that with TWRP.
Boot into recovery Wipe/Advanced Wipe. Then after that is completed, without rebooting, Format Data. That should sort out your partitions.
Then Install ROM from the recovery. It will need to be on the device. If your new ROM is not already there plug in a USB lead and transfer the zip file from your pc.
If you want to re-install your backup, do that instead.
If that doesn't work Backup in TWRP, even though there is no system. Then copy your Nandroid backup (must have been made via TWRP) and paste into the same folder as the Backup you just made, overwriting if asked.
I have had to do all this myself!
Good luck
Hi all!
I have the simular problem.
Umi Zero can not start.
But recovery seems to be working.
1) TWRP recovery 2.8.2
After full wipe, my TWRP recovery write "Unable to mount /SYSTEM"
The same message I have if I try to flash original 3.10 ROM via TWRP.
It is impossible to mount or format or repair SYSTEM via recovery
But it is possible to see files in FileManager and go to Fastboot and ADB mode
2) ADB and Fastboot mode.
Impossible to flash any partition.
"boot" - checksum error
"recovery" - "not support flash" message
"system" - filesystem created, start "erasing" and freeze. If I disconnect phone, have got message "failed (too many links)"
adb sideload does not work also
3) SP Flash Tool
I tried with full 3.10 ROM and with CRT 3.0 recovery
Download mode and Format+Download mode.
The same result: yellow bar finished and got message "Checksum error" or something like that.
All this experiments change nothing in phone. I still have TWRP recovery and "unable to mount /SYSTEM" message.
Any advices?
I am not English-speaking guy, as you guess), sorry.
It looks like memory become write-protected...

Hi
Did you Advance Wipe and Format Data?
I found that worked.
Alternatively, you could use Rootjoy to put just about any ROM on. CM 12.1 works ok.
Once you have a stable installation, install a custom recovery like TWRP 2.8.7 from Needrom. I used Mobileuncle, an app from the Playstore. However, I looked just now and it doesn't seem to be available.
I have tried Rashr, but couldn't get it to work.
Once you have it all stable you can flash the ROM you really want via TWRP.
Good luck
Advance Wipe and Format Data or flashing new stable ROM via TWRP did not work for me. The same result- unable to mount /system.
Rootjoy and Mobileuncle could be used if phone is working. My phone works in recovery mode only.
I tried to flash different recoveries but did not find the way to do this. As I wrote, Sp Flash Tool, Fastboot and Adb Sideload did not make any changes to my recovery. I think, flash new recovery will help if I found the way)
Or if I discover the method to test and\or repair /system partition from PC
But thank you for answer)
@YrP
Rootjoy works from your pc
Yes, Rootjoy- works)
But for establish connection phone must work too.
And not in recovery mode.
@YrP
I have already done all this with my daughter's Zero.
However, it's in bits at the moment while we wait for a part from China. So I can't go through the process with you live, step by step.
I am in the UK.
If you send the phone to me I will try and fix it for you.
PM me if you want to go ahead and I will let you have my address.
I am in Ukraine, it is too far from UK)
I will keep trying to find the way to fix it by myself.
But thank you very much for your attention and advices.
@YrP
I have got my daughter's phone back together and fixed (mostly).
Did you manage to get your Zero going?
Sent from my Nexus 4 using XDA-Developers mobile app
@goldbear
My UMI is still bricked(
It is flash memory problem, I think.
I am trying to find the tool to remap internal memory, to move SYSTEM part to other physical place. But did not find it yet.
What was your way?
Zero stutters, processes crash or the phone will not boot into System
Have you already tried a Factory Reset or re-installed the ROM?
What can you do?
You could try the following. However, if your phone blows up, orders a takeaway or elopes with your girl-friend, please don’t blame me.
1. Provided you already have TWRP custom recovery installed and your phone is powered down boot into Recovery: hold the volume down and power buttons until the Zero logo appears then let go
2. Select Wipe/Advanced and select Dalvik Cache, System, Cache and Data. Slide to execute
3. Select Format Data/ type yes and slide to execute
4. Reboot into Recovery without installing a new ROM
5. Select Backup, choose SD card rather than internal storage and give the file a memorable title like Blank Backup and date. Select Boot, Logo, Recovery and Uboot. Slide to execute
6. The next step requires you to have a Nandroid backup made via TWRP already made of a stable ROM. If it isn’t stable or you don’t have one I have attached a clean backup below. It’s derived from Cyanogen Mod 12.1. This is based on Lollipop 5.1, with Gapps and rooted. I have found this to work. As the title of the file suggests, it’s a factory reset, ie no personal data included. Download it to your pc unzip and save it.
7. Connect your phone to your pc via USB cable and open Windows Explorer
8. Find your stable backup or the one below and drill down until you see the folder with 15 files, starting with data.info and ending with uboot.emmc.win. Select all and Copy.
9. Open another window and find the TWRP folder on the SC card of your phone. Drill down to the same folder containing similar files as to step 8 above. Click in folder and Paste. When prompted select Copy and Replace, all and Ok
10. If your pc doesn’t show your phone and the SD card, in recovery select Mount and USB storage.
11. In Recovery select Restore and the Blank Backup (or whatever file name you gave it, now populated with usable ‘data’). Slide to execute
12. Give it time to load and boot up
13. You should be good to go!
If you don’t like CM 12.1 installing a new Launcher from the Playstore, like Cheetah will make it run smoother. Everything after that is down to you.
Of course, you could flash another ROM via TWRP
The backup below was made via TWRP 2.8.6. This is also attached below. You can install this via a previous version of TWRP as an image. Unzip it first.

I really need help, I have tried the following, having TWRP V2.8.5.1 functioning and Fastboot also.
- Through TWRP, tried connecting the PC so I can Flash a ROM from there, but I can't seem to be able to connect the One to my PC so it will let me transfer files through cmd with adb push. My computer is a windows 10 OS with Samsung drivers and Android SDK full installed, still can't get it to work.
- Through Fastboot tried flashing cm-11-20141008-SNAPSHOT-M11-bacon.zip downloaded from Cyanogenmod page and using Oneplus One Toolkit 2.0, even though the Toolkit says the files are there, still phone continues to show 1+ logo and then rebooting.
Please I need some help.
Cheers. and thank you.
Why adb push when you can just copy the file over using a file manager (or a command prompt if you insist) and then flash from the internal storage?
I'm having the same issue but in my case I can boot into recovery or other stuff IF I HAVE THE USB PLUGGED IN
Maybe you can check and and let me know, if I found a solution I'll tell you, hoping the same from you please.
http://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541 this could help.
So i was installing a rom and accidentally put to erase everything even internal sdcard when i did the wipe Now I cant even do anything but get on TWRP. When I reboot it just stays in google logo. PLEASE help me out and show me how I can put a ROM in my phone. Whoever helps me with correct information I will give you $50 through paypal or bitcoins if you wish.
Do you have a mac or PC?
If you have a Mac then DL "Android File Transfer" Connect your phone to your computer. Boot into TWRP. Your computer and Android File Transfer should see your phone. Drag a ROM .zip to your phone (and any other needed .zip's) flash the rom.

You can either download and reflash the factory image via fastboot from google:
https://developers.google.com/android/ota
Or download your ROM of choice with the correct vendor image to your computer.
Then while in recovery on the phone and connected to your computer navigate to where you downloaded the ROM, open command prompt or terminal and
"adb push FILENAME.ZIP /sdcard" push all the files you'd like . After finished either reboot recovery from TWRP or adb reboot recovery.
This assumes you have adb installed and as a system variable. If you don't have it installed in PATH then place the files in the appropriate adb location and navigate to it in command prompt and issue the adb push command.
Guys i was able to flash the rom and gapps to my phone using this method:
....highonandroid.com/android-roms/how-to-copy-files-over-to-your-android-in-a-bootloop-with-no-os-using-adb/2/.....
the only thing now is how do i flash .img files such as bootload, vendor and radio files? When im in twrp it gives me 4 options and says "Select partition to flash image"
Boot
System Image
Vendor Image
Recovery
Please let me know where to flash them.
i forgot to mention i have a PC
also to the 2 people above please pm me your paypal address or bitcoin address. Will give you a little something.
Those are the only images you flash via recovery, boot is kernel, the others are self explanatory. Bootloader's are flashed via fastboot.
If you were able to push a ROM via adb just flash the .Zip and boot the ROM as normal.

Hello, IMG files are flashed with fastboot from bootloader...
Why not starting fresh...
1 - first, power your phone down.
2 - press power + volume down to reboot to bootloader
3 - plug your phone to your computer
4 - download latest Google factory image here: https://developers.google.com/android/images
This is the latest 7.1.2 worldwide build: https://dl.google.com/dl/android/aosp/angler-n2g47h-factory-f1111327.zip
5 - unzip and navigate inside the folder and locate the flash-all.bat
6 - make sure your phone is in bootloader and properly connected
7 - double click on flash-all.bat and let it run until it reboots
Now you'll have a full stock with latest 7.1.2 to start with...
Just in case, i don't need money. If you still want to donate, choose a charity association of your choice and only send a copy of the receipt here. That will worth 100x more for me than a personal donation... :good:
Good luck...

If your PC sees your phone when you are in TWRP then all you need to do is drag over a ROM .zip and the Vendor .img and then just flash them.
I often when doing a fresh fresh install erase everything including internal storage (SDcard) then drag over my needed files to flash and do so.
Since you have a PC i believe that Wang's (i forgot the exact name) toolkit can help you too.
Keep in mind: Really hard to kill a Nexus. If the bootloader is reachable you can always go straight to the stock and start again.
You can find a nice tut at Google's page:developers.google.com
Don't stress, there is (almost) always a way!
I want to unroot my phone and I did manage to flash stock recovery.
But now I want to flash stock firmware through adb sideload.
But when I typ adb devices it does not recognize my device and when I type the sideload command, it says error: device not found.
I am using minimal adb fastboot version 1.4.2.
I already tried to use all the different kinds of drivers @ device manager
I am really out of idea's and hope someone here knows what to do.
Edit:
When I use TWRP recovery and I use sideload, adb can recognize my device (and fastboot can also recognize my device).
So only through stock recovery adb cannot recognize my device.
And I remember that USB debugging is off, I do not know if that has to do something with this?

For the stock recovery, Side load Works.
But only Side load, not "adb devices".
After you have selected Side load from stock recovery,
(Boot in stock recovery,
Select your language, -> install from usb -> yes )
Only after this, your device will show in "adb devices"
It will show as Side load device. Then Side load as usual., It will work.
P.S. - USB debugging is not checked in recovery mode.

Sorry for late reply!
I did what you said, but I get this error:
error: device '(null)' not found
And when I select install from usb -> yes, Windows notify that there is a problem with the device and cannot recognize it.
What drivers must be installed, OnePlus drivers and ADB drivers?
Does someone know how to fix it?

The problem is stock recovery that you Install does not work well in windows 10
1 Boot in bootloader install TWRP again here
2 Reboot in TWRP Recovery
3 Wipe> Advance Wipe> Select Dalvik & Cache System & Data> Swipe to Wipe
4 Reboot in TWRP Recovery Transfer OOS 4.5.8 Full Rom Zip to the device over MTP
5 Install Menu> Select OOS 4.5.8 Full Rom Zip> Swipe to Flash
6 Reboot System
Now you are in full stock OOS
If you restart now in stock recovery you will see that sideload will work
Adb sideload with stock recovery not work in Windows 10, if you use Windows 7, you'll find that it work well.
The problem is stock recovery from the official site
This OP5_recovery.img
If you are in TWRP and install OOS stock rom sideload will work in windows 10
Had driver issues to what j did was with twrp installed I transferred the Oxygenos rom to internal storage installed it from twrp and then put the OnePlus recovery back on
