Bootloop after UnBrick

Hello,
I try to Unbrick my A500 with Acer_A500_0.000.00_1.122.01_EMEA_GEN5_update.zip.
At the first time it works, I can boot and I want to flash the system.ing and boot.img for Acer_A500_1.141.07_COM_GEN1 with the Acer ROM Flasher to get german language support.
The HowTo in den Android-hilfe tells my that I will get an error after reboot (right) and than I have to flash another update (can´t post link because I´m a noobie)
Now I´m stick in a bootloaderloop (android logo) and nothing will help.
I try flash the unbrick update again, but the only thing I get is the Bootloop at the android logo.
I need some serious help for this.
Thanks guys

Doesn't sound like your getting into recovery with the update.zip. make sure you keep holding down the vol- button until you see the little green man. Don't let go of it when you see the big "Acer".
After doing the update.zip to unbrick, run itsmagice BEFORE running Acer Rom Flasher. Then flash the boot and system images from that thread. Then reboot after the 6 minute window. It should boot normally.
Or just stick to the instructions in the other thread... I think your just not getting into recovery correctly.
PS.. Acer Rom Flasher is going to get an update when I get the chance.

this seems to be the solution. Thanks for your [TIP]
Well now I´m chinese, but I try the Acer_A500_0.000.00_1.122.01_EMEA_GEN5_update now.
Edit: It does work. Now I try the boot.img and system.img.

i had same problem
I had the same problem with that zip. It was corrupted. Found an other source update.acer.zip and it worked, but some chinese apps came with it. List few other thing. The update.acer.zip would hot boot. The zip had folder with an other update.acer.zip in it. After extracting the zip from the zip it worked.

Help me,, Cannot boot in to recovery

Please help needed!!
I'm stuck here for 3 days
Ok I'm going to tell everything I did,,
My Gionee E7 is indian version.
First I rooted my phone with kingo Root.
Than I flashed CWM chinese version.
I upgraded my system to kitkat and changed the recovery to stock.
I used it for a week than some how my music player and gallery were corrupted.
I don't have any rom so I download one but it was in chinese, flashed it to my gionee. than after rooting,,
I flashed the CWM, same I flashed weeks ago
Here my problem started :crying:
The CWM is not starting. I used recoery tool to boot into recovery after boot up it shows black screen. I used every method holding Vol+ and power button but the same result.
than I tired to get back to my stock recovery but it does the same.
flashed many times both recoveries but didn't worked.
I searched a lot and find a TWRP. I flashed it and wow it worked Finally I can boot into recoery mode.
Now I find the Nandroid backup of indian version. I made it a zip and flashed it through twrp.
My phone is back to indian version but its slow, not too much but its slow; camera, gallery and other apps take some time to open. I can't make or rcv phone calls. Now what i did is download the update form System update.
Now i got kitkat rom.zip but twrp failed to install it.
Some one on the internet was saying that its the problem with my Kernel. I have the latest kernel so CWM won't work cuz it uses old kernel and display drivers.
My
android version is 4.2.2
Kernel version is 3.4.0-svn2155
I also got TWRP for lolipop,
and I patched binary_update in my kitkat rom too but TWRP can't flash it
Thats my whooooolllleeeee story. "

Hello my friend, please help me.
I am trying to flash stock inidan rom 4.2 but.. I installed all CWM for E7 found on the internet and I am getting black screen. I managed to Install TWRP but TWRP cannot flash the rom that I need to flash. I flashed a chinese 4.2 but is piece of garbage..
gngc-download-tool said that the com port is closed.
I have windows 64 is this the problem causing gngc not working?

No its not, it is working on 64bit windows very well.
In TWRP factory reset and format system and data, than install
Chinese 4.2 ROM. After that boot it and try it again.
It should work!

Help
I just rooted my gionee elife e7. Flashed the chinese recovery which seemed to be the only one which would be compatible. But, while changing a few setting using pimp my rom, the software just stopped working. Errors keep showing up on the screen - "system.ui is not working", "android app is not working", I cannot even go the settings because "settings is not working". Third party apps still seem to work, so, whatsap and stuff continue to function. Doing a factory reset or flashing firmware again seem to be the only viable option.
But, when I try to load up the bootloader using the power and volume keys, it gets stuck on the screen showing the gionee logo and it reads 'fastboot mode' in the bottom left hand side corner. So,
a. can you offer any advice which may be useful ?
b. can you share the link from where you got a TWRP recovery which will work on the Elife ?
c. do you have any idea what exactly went wrong here ?
Any help you can provide will be appreciated because, it's my mausi's phone and I will have a very tough time explaining what really went down here.
Regards,

Lg g2 no os at all

Hi!
First I tell you how I recently messed up my LG G2 D802.
I hadn't had a custom rom for ages and now I wanted to have one (This wasn't the first time. I've done this a lot earlier). I had always had root access, but not custom recovery. So the first thing was to install one and I chose to download Rom Manager from Google Play, and then install ClockWorkMod. So, when I was installing the custom recovery I came up with a problem: something went wrong during the installation (I have no idea why). When I booted the device, white letters and numbers appeared on the top left of the screen, saying something like: "boot certification error" and numbers like "[780] [800]" and so on. The screen went black and the phone didn't load the OS. So I was shocked of course because I had never had such a problem.
So, desperate for trying everything to find the solution, I tried tens of ways to try to fix the problem. Finally I read about thing called SRKTool. So I used it and ended up having TWRP on my device, and no OS at all. I tried to flash CM12 and CM12.1 (downloaded from the official site) but nothing works out. TWRP says that flashing the ROM is succesful but when rebooting the system it doesn't load the OS but it comes back to TWRP Recovery mode - WHATEVER I DO. I can't enter the Download -mode at all. I tried hard reseting (Power + Vol - keys), but once again it boots to the TWRP. I can't understand why the TWRP fails to flash the ROM even though it's saying the process was successful. Or maybe this problem is much more internal - and permanent.
After tens of XDA developers' threads I'm writing this here because I'm in need of help. I want to bring my G2 to back in life. I'm out of ideas. Can you help me? I tried to flash the stock firmware but guess what happened? The installation failed, and the device booted back to TWRP. So all I'm able to do is to use the TWRP Recovery. I appreciate your help. Thank you.
(Ps. I'm sorry if I break the rules by writing a new thread. My problem just seems to be so unique that I couldn't find help anywhere.)

If you have access to twrp than you can do what ever is needed
what twrp version douy you have?
enabel MTP, so you can copy from PC

The solution is easy. Download the stock rom for your model and install it with otg cable. The reason cm12 is not booted is because you need jb bootloader or caf bootstacks.

The current version is 2.8.7.3. Should I try other versions?

Did you solve the issue? Or is it still not allowing you to get into your F/W?

Hi!
I tried to install TWRP version 2.6.6.3, but it fails to flash it so I'm stuck with the version 2.8.7.3. All I'm able to enter is just the recovery mode. I can't enter the download mode so I can't flash the stock firmware.
Currently I'm out of ideas. I can't flash any OS, the TWRP fails everytime and creates errors.

Try flash bumped kernel like lp dorimanx then flash bumped bootstak then lp rom like cloudy or stock. Or google this: lg g2 unbrickable now xda ...that work for me

GPS Problems & recovery image

Hello , i have a Lenovo A6000 and after some GPS issue i decided to flash it with TWRP 2.8.6.1 and add a custom (CM11) rom.
After a little bit of picking around and trying various gps fixes i think the problem is hardware wise.
I unrooted the phone (i used kingroot to root, comes with an unroot button) but now i need the factory recovery image so i can return it back for repair (factory rom was backed up from twrp and recovered successfully).
The current (and up to date according to its settings) rom is S025_151016 and its a single sim model. Do i need the same recovery ? I have found the S010_151016 recovery on the internet, is it ok to flash this one ?
Also general tips to fix gps if possible ? I tried TopNTP & various cm11 roms
Thanks for the answers

You can download your recovery as per your current android version from here, and then flash it
www[dot]techolite[dot]com/34431/lenovo-a6000plus-pure-stock-rom-recovery[dot]html
Replace [dot] with " . " in the link
And first try this to check if the recovery wont cause any problem - "fastboot boot recovery.img" where recovery is the name of your recovery image. If the phone successfully boots into it that means you can flash that recovery without any problem.
For permanently flashing recovery - "fastboot flash recovery recovery.img"
Hope it helps!!

Try "fastboot boot recovery.img" first
If it works and the phone reboots then permanently flash the recovery using "fastboot flash recovery recovery.img"

rr 7.1.2 without gapps/ recovery mode not possible

Hello xda developers this is my second thread sorry for the first one that i made yesterday, I am having a problem with my lenovo k4 note a7010a48
after rooting successfully I proceed to flash rr 7.1.2 but did not flash the gapps now my problem is how to go back on recovery mode to start over again
I already used the power button followed by the volume up down buttons but it is not working like before it is nougat. I only need to get to recovery mode. Please help and thankyou in advance. More power

Does u have root access now and which version of rr u flashed

yes the phone is rooted already and flashed with rr 7.1.2 only need to open recovery mode which is I have no idea

Contact in telegram app 9032015333 I will tell u

i dont know that or how to do that can you teach me please thank you

I have the same issue. Can't enter into recovery and the phone is unable to start.

Same Issue || Don't Know How To Fix
Hi,
I am searching for a possible solution from a day. But could not find a working solution.
After successfully flashing RR-N-5.8.5 (Android N)
Unable to go into recovery.
PROBLEM DESCRIPTION:
1. When Press Vol Up + Vol Down + Power Up
2. Recovery is not loading up
3. Instead it goes in boot loop
4. Normal boot mode and fast boot mode are working perfectly fine
SOLUTIONS TRIED:
1. Flashing recovery again using fastboot mode
2. Flashing different recovery, i.e updated version of recovery
As all recoveries which were available were for marshmallow version. I am not sure but have doubt as android version is updated so the kernel so do recovery also become obsolete in this case ?
Any help is welcome and appreciated
Thanks

for fastboot mode and for recovery mode yes i tried it also but thats the problem no recovery mode. I will wait for the solution when it comes i will just store my phone for a while.

Hi Developers,
Is it possible to reset the phone at hardware level? I can't even connect the phone to PC as it keeps on rebooting.
Please note: upgraded to Nougat and wanted to do the second recovery as suggested by mohancm in the post. When the phone rebooted (before flashing the second recovery), the problem started.
Please let me know if any one has a fix/workaround for the issue.
Thanks,
Srihari

1.Download TWRP recovery unzip files.
https://drive.google.com/file/d/0B1CKVcdcbHFPUzFCODVMN0ZfTW8/view
2.Now in folder TWRP\img\ there is the file recovery.img.
3.Download the second recovery for nougat recovery-Nougat.img and put in the TWRP\img folder.
https://androidfilehost.com/?fid=673368273298981920
4.Rename it as the original, recovery.img and replace it.
5.Then connect your phone to usb and select the 3th option from usb debugging message
"Transfer photos(ptp)"
6.run TWRP_Install.bat from TWRP folder
And you are done, had the same problem and I figure this solution, hope it will help.

I cannot locate the transfer photos(ptp)

ok I already done the part I am now on the recovery mode thanks. new problem of mine is after flashing the rom gapps and recovery after reboot it goes back to recovery mode did I miss something on flashing?

ok so i already passed this problem thanks for the help xda community thank you very much but I have this bootloop problem maybe I did a mistake flashing before rebooting sorry i am a noob in this kind of upgrade specially in mobile phones. I will be careful next time after I passed this problem I hope you will help me once again, my phone in bootloop is killing me.

I have same issue... I flashed gapps and my phone is working smoothly... The issue is i can't go into recovery mode... I tried some one tap reboot to recovery apps but all whats happening is phone restarting normally.

For those who can't access recovery mode. You were supposed to flash updated recovery image after flashing rrn rom.
Enter into fastboot mode by using adb shell.
Flash the updated recovery image
Now try rebooting into recovery.
Should work.
Worst case, restore by flashing stock rom using SP flash tools. And then start all over again.
If you face any issues ping me. Even I had faced this issue and fixed it after a lot of struggle. I can try to help you.

Or you could download Official Twrp App directly from play store, then find A3000 (Air Row) in 'select device' and flash that to recovery, (if your phone is rooted) then you are good to go, go to recovery mode and thats all, your twrp is now has been flashed.
Thank me later??

This really worked for me. Many thanks man.
Well it got me some time to find the right recovery image for my ROM so I decided to give you link for anyone going through the same.
My configuration at that time was: DotOS 1.2 and TWRP 3.1.1 (or so).
On the DotOS thread was enclosed link to wrong recovery image file (or its version was changed as of 28.12.2018) but after small investigation I found this file recovery-mohan-N.img.
Note: This recovery worked for TWRP and Android Nougat and I'm not an expert to suggest this will work for your case either.
Thank you again and have a nice time
