@sandeepmraval [ this is continue of ur last response ]
- According to your HBOOT ur phone already has lollipop so in this situation there is no rollback to KITKAT.
- Can you flash TWRP recovery see here how to flash? https://www.youtube.com/watch?v=xsn6co4Ve6M
- Download this twrp lollipop backup https://mega.nz/#!7NcyhJhT!p0AVHYCe6...Lkmc9xWXjlZ5FE
- Put in SD card; make folder in sdcard on basic of this location [ TWRP/BACKUP/SH4AVYC01134/PUT THE DOWNLODED backup folder here ]
- Mean time you should already have flashed TWRP 2.8.7
- SO go to bootlodder>Recovery> you will reach trwp
- and wipe cache | system | delvik cache | factory reset
- Restore that backup from twrp & again just factory reste "yes" from Twrp recovery
- Finally reboot system from twrp recovery
- phone will boot & wait for complete boot with HTC sound
- If above twrp backup worked : you are lucky,if not then
- Looks Like this is the file you need "0PFJIMG_A51_DTUL_L50_DESIRE_SENSE60_MR_hTC_Asia_I ndia_2.10.720.1_R_Radio_01.01.010_U10305041_08.01. 50512_release_453048_signed.zip " but i found it on http://www.ir-file.com/ where we need to pay to create account & download
Last question i would like to ask you from where did you get lollipop ruu for your phone ? what was download link ?
If any problem occurs let me know i will find the another way.

@ h1dd3n_sn1p3r
Ok I will explain the whole thing.
1. I had updated my HTC D820u from Kitkat to Lolipop without rooting. i.e. stock update.
2. Then I rooted it by following all the steps i found in one of the post on xda i.e. unlocking bootloader, then installing twrp recovery, and then rooting it. I have installed Android Studio Bundle for the steps.
3. Now I wanted to go back to stock i.e. Lolipop 5.0.2 which was my last updated stock version.
4. I downloaded Stock Lolipop firmware for HTC 820 from here. http://www.theandroidsoul.com/htc-desire-820-dual-sim-gets-android-5-0-lollipop-update-in-india-today-84783/
5. Then I started searching ways to go back to stock.
6. http://forum.xda-developers.com/showthread.php?t=2182823 This link helped me but still I couldnt go back to stock firmware.

The only way by which i can start my phone is volume down+ power button.
The moment i select recovery option the phone hangs on and there is htc logo on the screen.

Root rogers streak up to stock 2.1

Ok here is a simple guide on rooting and upgrading your rogers dell streak with the official roms
IM NOT RESPONSIBLE FOR ANYTHING THAT HAPPENS YADA YADA YADA
THIS IS NOT A COMPREHENSIVE HOW TO FOR PEOPLE THAT HAVE NEVER ROOTED OR FLASHED A DEVICE , MORE TO POINT USERS OF LOCKED ROGERS STREAKS IN THE RIGHT DIRECTION , AND TO SUPPLY THEM WITH THE ROMS AND RECOVERY THAT WORKED FOR ME
ALSO IT IS RECOMMENDED BEFORE YOU ATTEMPT THIS YOU LOAD CLOCKWORK RECOVERY THROUGH FASTBOOT , AND DO A NANDROID BACK UP ,THEN GO BACK TO STOCK RECOVERY BEFORE YOU ATTEMPT THIS, BUT IT IS NOT NESSECARY
THE CLOCK WORK THAT WORKED FOR ME WAS THE 1.8.1.7 VERSION INCLUDED IN HERE
/SIZE]
CLOCKWORK RECOVERY THAT WORKED ON ROGERS BUILD http://www.zshare.net/download/8340237894835c1d
Step - 1
Download universal androot(from link below)then place on your sd card then install the apk with apps installer from market. Once installed run the app, click root and your rooted .
UniversalAndroot_1.6.1.apk - 0.32MB
Step - 2
Download 02's 1.6 build 4399 (From link below),rename to update.pkg,then place on root of sdcard ,turn off phone ,power phone into recovery by holding power button and both volume buttons at same time. Now you should be at recovery screen ,select option 2 , you can navigate with volume buttons and make selection with camera button ,you will now be presented with a warning screen telling you to press the camera button to install update package ,press camera button, let it install , wait for the dell logo ,wait , wait , wait , wait you are now on build 4399 wich is 02's 1.6 build
BUILD 4399 - http://www.megaupload.com/?d=6KBABM67
Step - 3
Download 02's 2.1 build 8105 (From link below),again rename it to update.pkg ,place on root of your sdcard ,turn off phone ,power into recovery and install same as previous build , when install is done dell logo will appear , wait , wait ,wait ,wait ,wait , you are now on build 8105 wich is 02's 2.1 build
BUILD 8105 - is on this page over at modaco http://android.modaco.com/content/d...2-1-downloads-how-tos-rom-superboot-recovery/
YOU MAY HAVE TO RUN UNIVERSAL ANDROOT AGAIN TO GAIN 2.1 SUPERUSER PERMISSION , THIS IS WHAT I HAD TO DO , BUT ITS ONLY ONE CLICK
voila you are now on 02' stock 2.1 on your rogers streak
if you have read this and have no clue , then take a look at the threads below they are more comprehensive
OTHER THREADS THAT HELPED ME ARE BELOW

http://forum.xda-developers.com/showthread.php?t=776883
here is a nice tutorial for rogers streak :
http://whirlpool.net.au/wiki/dellstreak22
and then u can use z4root found on marketplace for permanent or temperary root
I've installed O2 2.1 build 8105 on Rogers Dell using the guide in the first post and right now it seems like I dont have 3g conection any more. Also stock browser redirects me to Sisco login page evry time I'm trying to open any webpage and ask me to input guest password. Does anybody know how to solve this issues? Maybe I need to setup 3g settings manualy or it should be done automatically anyway?
Thanks for your help

On this step I get an error that says "cant find /MISC" and it just sits there.
Now I have flashing leds from my earlier rooting with super boot. does anyone have a stock rogers image I can use? I tried a factory reset but still the leds flash :/
Thanks for the write up !
removed link in my post as it said I couldnt have links :/
When I try running the update to move from Rogers 1.6 to the O2 version of 1.6 it says software already up to date. Then it reboots without installing. Do you know a way to get around this?
Sorry, it was a silly mistake. I tried to update like a regular update package instead of getting clockwork working.
fastboot boot problem
I have a stock Rogers Dell Streak.
I want to fastboot boot the clockwork recovery and nandroid my current setup. Then I want do a factory restore and nandroid that after booting the clockwork recovery.
I follow the guide "What you need to know about the Dell Streak - PDF"

I put the files with the recovery in c:\streak

The "What you need to know about your streak" guide says you should type :
fastboot.exe -i 0x413c flash recovery recovery-clockwork-streak.img
I don't know what the "boot" option would be used for.
boot
I want to boot the clockwork recovery without actually flashing it.
Then I want to nandroid backup the phone as stock Rogers, in case I want to go back to it. Then I want to factory reset and then nandroid that.
This is what is referred to by the op.
I wonder if anyone has done this on Rogers 7921?
Well, are you sure, OP does not mention using fastboot with the boot option.
Then again, I'm a newb, I might be wrong.

Thanks Shaky for the efforts.
I agree with Tegra having its own thread, especially since so many OEM outlets will be selling this tablet and other iterations, like the coming Phone version of the Tegra 114i SoC.

[TUTORIAL] Unbricking VNS-L21/VNS-L31

Hello everyone! I know there are a lot of threads and comments about unbricking your device but in order to get you on track quicker then anything else and point you to the right direction i`m writing this tutorial which i find is quite successfull. This tutorial was made basically on my personal experience and with the help of some advices and suggestions.
First of all there are some questions that you must ask and answer yourself in order to do everything correct:
1. Do i have unlocked bootloader and frp? If yes, continue reading. If no, read Important note 2!
1.1. Do i have access to stock/custom recovery? If yes then continue to read.
1.2 Do i have problems mounting partitions with Revolution Recovery? If yes, read Important note 1!
3. Do i have installed SDK Platform Tools (ABD and FASTBOOT)? If no then download from here (Always use the latest version!!!)
4. Do i have installed HiSuite? If no then download it from here.
Okey mate if all your answers are Yes then follow Guide 1!
5. If you think your device don`t have access to these then read and follow Guide 2!
For those of you with locked FRP you can check this website and see if it helps!
How to get into fastboot?
Variant 1
Hold down (VOL-) + POWER when connected to PC!
Variant 2
1.Start HiSuite.
Step 2 (Click for image preview)
Step 3 (Click for image preview)
Turn off your phone and then by holding down (VOL-) + POWER connect usb to the pc!
! Important note 1 !
If you can`t mount partitions then the thing you must do is go to Revolution Recovery then do as i say:
Wipe -> Advanced Wipe -> Select partitions one at a time! -> Repair or change file system -> Change file system -> F2FS -> Then go back -> Select EXT4 -> And voila u`re done!
! Important note 2 !
Okay easy way to find out is if you see warning screen about unlocked bootloader then it is unlocked so it is frp. If you go to fastboot and you see Bootloader: unlocked/frp: unlocked but you don`t see the warning screen then my friend u`re not unlocked! Quickly open up the console window connect to fastboot and type:
Code:
fastboot oem unlock <your unlock code here>
Easy, a?
GUIDE 1
First of all download these files in order to continue. (Place them somewhere easy to find! )
Recovery - Revolution Recovery NOUGAT
(I can guarantee you that this version works that`s why i used her in this tutorial! METICULUS was not working for me it doesn`t even started at first place.)
Stock OEM info - Download
Stock ROM - L21C432B130
1. Open up fastboot then flash Revolution Recovery from the zip.
Code:
fastboot flash recovery recovery_twrp.img
2. Start up Revolution Recovery by connecting your device to the PC and holding down (VOL +) + (VOL -) + POWER
3. Flash Stock OEM info from the zip via Revolution Recovery. Make sure when installing it the result was Successfull!!!
4. Remove usb cable from PC and Shutdown the device via Recovery and don`t plug the cable or start the phone!
4. Get your SD Card ready and plugged to the PC then Create a New Folder named "dload" in the root directory of the SD Card and paste update.app file in there!
How it should look in the Micro SD Card: dload -> update.app
5.Place the SD Card in the phone
6. Start the phone!
7. Okay logo is there showing up wait about 1 - 2 minutes and phone will be automatically starting to update from SD Card. When it is done it will restart the phone. Make sure at the moment when it does and screen goes black, hold down VOL UP!
8. Format data and cache!!! If you skip this part there will be a bootloop!
9. Voila. You got your device unbricked and aliveeeeeeee :highfive::highfive::highfive:
That was the easy part! If u`re unlucky enough for Guide 2 well my friend get some coffee and play some calming music list!
GUIDE 2 (When no one can help you but you :silly
First of all you should know that every case is different from one another but everything comes to one mission. Access to fastboot or access to custom recovery in order to unbrick. I will give you steps which I did when I bricked my device and I had no fastboot access, no access to stock or custom recovery, no erecovery access and no wi-fi upgrade.
So what I experienced?
You see logo but only that. Warning screen saying bootloader is unlocked. When you see warning screen u`ve got a choice what to do – Press to enter recovery, press to continue booting etc. None of that. When I was connecting the usb cable to the PC no detection at all. No working key combinations.
1. DRAIN BATTERY! REALLY. IT`S THAT SIMPLE. Leave the device on and put it in a shelf or something like that so you can`t see it and can`t touch it. 2-3-4-5 days. (I left mine for 2 weeks! :laugh The battery must be that empty that when you try to power it up only power icon shows up or nothing shows up at all.
2. When u`ve done with Step 1 get a laptop or a PC with freshly installed Windows or Linux.
3. Install SDK Platform Tools (ABD and FASTBOOT) the newest version from their website!
4. Install HiSuite from their respective website!
5. So now when you`re all done with installing the requisites get your phone in your hands plug the usb cable in the phone and then hold down (VOL -) + POWER when plugging it to the PC or laptop.
6. Believe me. It should get into fastboot. I`m 99% sure. If all the steps I wrote are done correct!
Why should battery be drained at ZERO?
I will tell you the truth – I don`t know. Really. But all I know is that it`s kind of a switch. When something goes wrong draining the battery will clear something that it shouldn’t be there.
If this tutorial helped you then click Thank you so i can count how many good things i`ve done in my life he he! If i didn`t helped you then don`t stop reading until you find the solution! Good luck!
How did you unbricked your device? Tell us here and help others do the same!
Is there a special reason why we should use a Nougat Recovery? I'm on C432B160 and have tried the change filesystem thing with METICULUS Recovery and well... it didn't work
Thank you!
Created an account just to say thanks for this! I've have spent hours and hours trying to unbrick my phone..

Okay easy way to find out is if you see warning screen about unlocked bootloader then it is unlocked so it is frp. If you go to fastboot and you see Bootloader: unlocked/frp: unlocked but you don`t see the warning screen then my friend u`re not unlocked! Quickly open up the console window connect to fastboot and type:
Code:
fastboot oem unlock <your unlock code here>
Easy, a?
GUIDE 1
First of all download these files in order to continue. (Place them somewhere easy to find! )

1. Open up fastboot then flash Revolution Recovery from the zip.
2. Start up Revolution Recovery by connecting your device to the PC and holding down (VOL +) + (VOL -) + POWER
3. Flash Stock OEM info from the zip via Revolution Recovery. Make sure when installing it the result was Successfull!!!
4. Remove usb cable from PC and Shutdown the device via Recovery and don`t plug the cable or start the phone!

I appreciate any advice, please help!
Yes i believe so

Is there a special reason why we should use a Nougat Recovery? I'm on C432B160 and have tried the change filesystem thing with METICULUS Recovery and well... it didn't work
Click to expand...

Good question! The reason i told everyone to use there version and this custom recovery is because METICULUS is not working at least didn`t for me! It didn`t even started at first place! Nougat is preferable because a lot of people get in trouble when they upgrade to Nougat and then try to downgrade that`s one of the reasons too. So my advice is try Nougat custom recovery for your case! Good Luck and best wishes

Yes of course there will be no trouble at all but instead of METICULUS recovery use the one i posted here! You have access to fastboot and unlocked bootloader so just follow the steps from number 4! If this doesn`t work you can try to flash http://consumer.huawei.com/bg/support/products/downloads/detail/huawei-p9lite-bk.htm?id=93797 this rollback package and via the method with SD Card and then flash stock rom from the link above! :highfive:
Good luck and i`m waiting for the result! :highfive:

Okay. First of all buy a decent Micro SD Card at least 6gb of storage! This is one of the most important things i forgot to tell here. Decent means famous brand like Kingston or Philips or something like that because other then this will fail! After that do you have access to fastboot? If you have fastboot then type "fastboot oem unlock <your unlock code>" If you don`t know it i can help you with that! After that flash the recovery i posted and try to fix the partition by the way i explained above. Then follow the last steps for preparing the SD and flashing the ROM. Good Luck my friend:highfive:

I appreciate the help, but the phone is locked. Phone Locked and FRP lock. I already imagine that at this point I only have a nice paper weight.

Check again i correct it
I´m facing the same poblem. Bootloop with Bootloader locked, FRP locked, battery empty. I can get into fastboot mode but no chance of flashing anything. USB debugging seems to be deactivated. I cant charge the battery because as soon as I connect the phone to a powersource its starts the bootloop. Force flashing via sd card (volume up and down plus power) doesn´t seem to work either (guess due to the low battery).
Any suggestions are much appreciated.

[H918] Back to Stock Everything

Saw a post in the roms section (for different variant) of a flashable to turn back to stock.
I flashed/rooted a while ago, I did a factory reset and now it boots into TWRP.
Looking to get it back to stock.
Thanks!
Reboot into twrp that's installed on recovery. Flash
this to get download mode back. Use it and LG UP in upgrade mode to flash a kdz to restore literally everything to stock.

It already has TWRP previously flashed in some way, but I cannot get into it. I see the logo flash up from time to time.
Tried Uppercut's LG UP and it will actually connect and give me the chance to flash a KDZ, but the phone will just do a quick restart and f*k everything.
OTA updates fail and say the software isn't verified. Also get the warning screen at bootup that the device has loaded a different operating system.
Any ideas? I just want it back to stock.

How do I boot into TWRP? Feels like a silly question...
"adb reboot recovery" just boots to what looks like regular recovery. However, when I try to update or flash a .KDZ through LG UP, it will restart and flash up the twrp logo and say twrp 3.2.1-3. So I know the fcker is in there somewhere. I want it gone... all of it.
HALP!! Please.

OTA updates and unmodified official stock files won't flash via TWRP.
Try flashing a copy of your stock recovery, then try installing the OTA update via stock recovery.
By the way, is that Charlotte NC? I ask because I live in Rockingham.

Eh... Charlotte is about two hours from me. I'm at the bottom of the mountain, but I've been to Rockingham a few times. Dad graduated as a RCHS Cougar in '78.
Also, if you didn't already know, I'm the same fool from the noob thread. Glad you found me here. So, when I say it has download mode, I mean when I hit volume up and plug in, it flashes up and says it, then shows the twrp logo, then boots as normal. Calling 'adb reboot download mode' just reboots. You think the bootloader needs to be re-locked?

Yeah, I saw you in the noob thread, I came here looking for the issue you were having.
I'm not certain about the bootloader, I own LG devices, but none of them have fastboot or download mode so I don't have experience troubleshooting flashing issues on LG devices.
Have you tried removing root and any changes you've made to system via the file manager or terminal emulator that is built into TWRP then flashing a copy of stock recovery via TWRP then reboot recovery to allow stock recovery to boot then boot to fastboot and try locking the bootloader then try flashing firmware.

I may have got it! Maybe... don't pop the champagne yet. I couldn't get into TWRP at all. It would flash up then just boot regularly. Finally I tried to enter DL mode again but this time I kept holding down the volume up button and pressed every other button like I was entering a secret code on Mortal Kombat. It actually entered TWRP!
Luckily I had already put a laf.zip and H91820f.zip on the SD card. Flashed the ROM first... did nothing except put Magisk on it... don't want. Reboot, flashed laf.zip with my secret MK code, then I had access to the real DL mode! LG UP found it and flash the real ROM. Still working on it to make sure it's all good.
---------- Post added at 07:20 PM ---------- Previous post was at 06:38 PM ----------
Yep, it's good now. Even updated itself to H91820h with no verification snags.
I shall now sell it on eBay for one billion dollars! Muahahaha!

Hello dude,
sorry if i wrote this but you posted in a wrong place.
You should have posted in questions&answers main thread,
as you can see this is guides, news and discussion thread.
Ask some moderator to move it to the correct thread ..
You could, perhaps, add some information on how the device ended up in this condition ..
What firmware was the last working?
Do you have a twrp recovery? if yes which version?
I tried to install twrp but I messed around. i tried several firmware but they didn't boot. I can't get into recovery, it just goes into fastboot

Ok Domenico,
fastboot commands should be sufficient to restore the device,
but you should say which was the last stock / custom working firmware,
(ex. VNS-L31C432B380 or ex. LineageOS 14.1) or at least the android version.... 6 / 7.
Cheers

Domenico, this is not possible.
B130 is a basic version of android 6.
Android 7 starts from B3xx and above...
Is your device single or dual sim ?
I can provide you a firmware, but it's a bit dangerous
to use without right knowledge of actual firmware version.
Make a little effort and try to remember ..

As you told me you probably had the B389 firmware,
so i will provide you that one...
From your PC download those three files..
1 - update.zip
2 - update_data_full_public.zip
3 - update_full_VNS-L11_hw_eu.zip
Rename file 2 from update_data_full_public TO update_data_public.
Rename file 3 from update_full_VNS-L11_hw_eu TO update_all_hw.
Let file 1 the same name.
Download THIS SCRIPT (HuRUpdater0.4zip file).
Create a folder and rename it VNSL31C432B389.
Copy all 4 file you downloaded into the folder you created (VNSL31C432B389)
If you want keep TWRP (now recommended),
copy the .img file of the recovery into that folder, otherwise proceed with instruction...
Copy your VNSL31C432B389 folder into the SD card of the phone..
Reboot into the twrp, hit install, find out your folder (VNSL31C432B389),
choose only HuRUpdater0.4.zip file and let it flash.
You may have to follow some instructions on screen if needed, flashing could take many minutes, keep calm...
When rebooting, device could go in a bootloop !!!
If after 20 minutes it hadn't booted, press vol+ and power till it reboot into recovery.
Make a factory reset and everything should be good. Good luck...
I would recommend to read at least a couple of times before do... take your time...
