Bootloop after making nanodroid with twrp in lollipop

Just flashed "openrecovery-twrp-2.8.5.0-falcon_STOCK_KK" in my lollipop.
Then made a nanodroid backup to my otg pendrive.
Then when i reboot i stuck in a bootloop
How to fix it.
Do i have to erase cache after flashing recovery????

I don't know if it is still the case, but I have had to use the following fastboot command before I could access TWRP again in this situation. The command will wipe internal storage entirely.
fastboot erase userdata​

I had the same problem but I can't remember how I solved. I do remember that I deleted all the user data. I then tried to do another nandroid and again it ended up with a boot loop so I think it's a recovery bug. I wouldn't do nandroid backups via recovery until the bug is fixed. I think there is an app in the play store that can make backups without the recovery but I haven't tried it.

This issue is now fixed with the latest version of TWRP just released: http://forum.xda-developers.com/mot...ry-twrp-2-8-2-0-touch-recovery-t2980621/page1

You need to format data partition not erase.
Don't remember how to do that.
I just flashed stock lollipop then flashed twrp.[didn't made backup this time,it's not working i think.waiting for update from dev]. Now twrp just works fine[with that screen flickering]

I meant format only
But the thing is recovery is not mounting data partition
Do you have a solution for that

Thanks hit to you!
Your suggestion saved my day!

I flashed the entire firmware and it didn't worked for me. How can I fix that? I had to flash CM and then reinstall the backup I made.
Whats the fix for having everything working as before? Cause i'll need to flash stock again to be able to receive OTA updates.
Will "fastboot erase userdata" fix all these problems?

22/3 version is working fine with nandroids, today I did a backup and restored it succesfully :good: also flickering is gone

According to these people(not me) when you enter command fastboot erase userdata your phone should boot normally
I suggest you to flash Philz touch because backup restore are working fine there

No, Not erease cache, but "erase userdata".
Use the command "fastboot erase userdata" from command prompt, that's all.
After you do this, press power button to switch your Moto G off and press power button again to start it. Your phone should normally boot and will be fresh as arrived from factory
Hope this helps you.

L09 will not accept any ROM's, custom or stock. Please Help

I have a Huawei ascend mate 7 L09 and was running Lollipop Emui 3.1, B331. After an incorrectly flashed Marshmallow update my phone got stuck in bootloop. I unlocked the bootloader, flashed twrp to it, downloaded a B331 Nandroid backup, flashed B331 and then restored the B331 backup, all successful, went to restart twrp says No OS installed. From that point on I haven't been able to get any Rom, custom or otherwise to flash to the device. Can someone please help? I am so stuck!!!

Mate 7, LT-09 very hard brick, dead device.

Hi everyone,
I have a Huawei Mate 7 LT-09 16 gig, and I recently did these works:
1. The installed rom was android 6 B513.
2. I read a post in this forum (that is closed now) and updated it to B553 KingVIP Chinese through restoring nandroid TWRP backup.
3. After install I saw lots of bugs, so I wipe all partitions through advanced wipe in TWRP.
4. Then install marshmallow stock recovery using mobopx tool.
after that nothing works.
The USB drive just show hisuite CD-Rom and device not recognize for ADB Options in windows 7,8,8.1 and 10.
There is no recovery,
There is no option using combinations of the buttons vol+,Vol- and power.
I tried installing stock ROM through .app file and dload folder and still nothing works.
I tried Jtag and after lots of work, fastboot screen appears and reinstalling all versions of different recoveries and looks like the software is installing nowhere in neverland!, there is nothing!
I take my device to a technician and he said there is maybe no way to re-run the device. I really need help.
Apologize for poor English and thanks in advance help.

First try flash twrp for 6.0 mobopx and then try restore backup b513 frome here
https://mega.nz/#!UsJh1YAb!A41FoZnuzWAcNdN0TaHN0pyA6AmDPQqz8vwYULxO0-8
And if work we work later to restore your MT to lp
Send from ?

First thanks for reply and then,
I tried all recoveries already, including twrp,cwm and stock, all versions of android (4,5.1,6). I have my twrp backup. My problem is that there is nothing comes, no recovery, no fastboot, just huawei logo. No USB detecting by computer, no adb device detection, nothing. Last time, before hard brick, I restored twrp backup and there was a 255 error by twrp in system partition.

I tried and could install twrp. When I try to restore backup using twrp it says "extracttarfork() process ended with error=255" and restoring fails. As I see there is 1200 MB in my system partition and twrp can not wipe it and this is the problem. I try to erase partition using fastboot and it says there is no permission to do that. thanks in advance if any help.

Something similar happened to me, too. What fixed it for me was this:
1) Go into bootloader mode (-Vol and Power)
2) Flash Marshmallow TWRP
3) Wipe CACHE, DALVIK, SYSTEM, CUST, DATA
4) Restore the Marshmallow KANG backup or flash one the KANG roms
Hope these steps help. I was on wits end and followed these steps after a lot of research and it helped. Good luck!

can you link me to 2) Marshmallow TWRP ?

At last I could fix my problem with my phone. I download Kang B553 zip, install it through twrp and then I could re-format system partition and I use B511 nandroid backup to restore everything and now the phone works like a charm.

[GUIDE] Flashing oreo roms on mi a1 without wiping internal storage.

Hello guys .
This is a guide to flash lineage os 15.1 or any other oreo rom on mi a1 without any fuss, bugs, wiping internal storage. And update it by dirty flashing it. I personally use this method and others have also used resulted in booting safely with zero bugs in the rom, no force closes.
So here you go :-
1- boot to twrp
2- wipe system,cache,data
3- check on which slot you are.
4- if you are on A, change to B (after wiping).
5- boot to bootloader and boot to twrp which I gave.
6- wipe slot B also. (System,cache,data)
7. Don't touch slots and boot to recovery.
8- just flash los15.1 rom from there and nothing else.
9- go to bootloader and again boot to twrp
10- flash gapps and boot to bootloader.
11- again boot to twrp which I gave and flash magisk.
12- reboot.
Enjoy. You have los 15.1 without wiping internal or downgrading to nougat or wiping internal storage.
So now here's the guide to update it. (Dirty flash)
(Remember to remove your pattern, pin, password before flashing or backing up)
1- Backup your data using twrp which I linked down below.
2- boot to twrp which I gave you.
3- wipe system,cache,data
4- check on which slot you are.
5- if you are on A, change to B (after wiping).
6- boot to bootloader and boot to twrp which I gave.
7- wipe slot B also. (System,cache,data)
8- Don't touch slots and boot to recovery which i have
linked down below .
9- just flash los15.1 rom from there and nothing else.
10- go to bootloader and again boot to twrp which I gave.
11- flash gapps and boot to bootloader.
12- again boot to my twrp and flash magisk.
12- reboot. Let it boot completely and skip the setup.
13- boot to twrp i linked down.
14-just restore your data backup and reboot.
Congo you have successfully updated your rom without wiping data and also whosoever is facing bugs like fp not working and other bugs use this method. Everything will surely work.
Anyone who has a problem can message me on telegram. Username- droidreboot

Have a good day.

If you're updating none of your apps or data will get erased. But if you are moving from stock oreo to this rom, it's like resetting your device. That's it. ?

You have ro to wipe data if you are changing roms. Like if you are on lineage, and you wanna install resurrection remix then you'll have to wipe system cache data in both slots. And if developer of lineage pushes an update and you're on lineage then you don't have to wipe data. I mean if updating you have to make a backup then wipe. Then after first boot restore that. Don't do this if you're changing roms. You'll get a bootloop

It says if you're upgrading from stock then wipe data. And if you're updating from old lineage build to new first make a backup then wipe and after first boot restore the backup. Read carefully.
