Lenovo a526 stuck at logo, bootloader locked & stock recovery installed. - Android Q&A, Help & Troubleshooting

Greetings, my lenovo a526 is stuck at lenovo logo.
I already tried wiping cache in stock recovery, but in wipe data/factory reset it says default data flag fail something like that.
Reboot, im still stuck
Then i tried flashing stock rom using spft it was successful yet still stuck at logo.
So I thought i should flash twrp or cwm recovery to install custom rom in sd card
I used adb fastboot. To flash those recovery because my stock recovery doesn't have "install zip in sdcard"
In fastboot,
My device is detected when i execute
Fastboot devices
"mt6582_phone --- device"
I cannot flash cwm or twrp directly because when i do it says remote partition does not support flash.
I believe i need to unlock bootloader first.
So i execute
Fastboot oem unlock
The result is 3 dots loading like forever
Now im in a dead end, i know i have to confirm it in my device but it has no display only logo.
Please, i need help. Is there any way to execute fastboot oem unlock without confirming in my device?

C'mon someone here had experience using fastboot. Any ideas guys?

Fastboot bootloop help

Im stuck in a pickle. I tried to update to neutrino 2.8 but got caught in a boot loop. I followed instructions that worked last time and tried to repair my recovery and it wiped the recovery and all other system data, but fastboot wont reboot or install the recovery image it only wipes the and formats. help please
Your details are not that clear. Either you are not using fastbook incorrect, or you have somehow borked the bootloader/
If the latter, you can try using RSDlite to reflash the bootloader. See the threads on how to unlock your bootloder for these steps. This is as close to going back to square one as you can.
BTW, you might also say how you did this. If just using CWM to install zips it is really hard to screw up your recovery.
I am trying to use fastboot to flash a recovery But when i flash the recovery i get
error cannot load recovery
or
waiting on device
But it will sucessfully wipe and format, just not flash or for some reason reboot the phone
I have it figured out to the point where now i try to flash the recovery and it hangs at
Waiting for Device
I tried everything i can think of
reboot
Re-install drivers
re download file

[Q] Help required about Stock Rom of Atrix and its Installation.

Hi all
I am in urgent need of help to fix my Atrix 4G.
The Story:
I have an Atrix 4G. It was on 2.2.4 then official update came and I updated it to 2.2.6.
Then I was wondering about installing custom rom. This was my first time to install a custom rom. So I googled and found.
Code:
http://forum.xda-developers.com/showthread.php?t=1398819
Neutrino ROM V2.9 [14/08].
So I rooted and unlocked my fone. My fone was successfully rooted and unlocked and I restarted it and there was Unlocked written on Booting Screen.
In this procedure I had to reset the phone so it was back to 2.2.4.
After that I downloaded the above rom put in in SD Card and Downloaded Recovery APK from market and it asked to restart the phone with power adapter plugged to start so I did the same. And recovery started. Then following the instructions I installed the custom rom and it was installed successfully it was my first time so I didnt took any backups unfortunately. So after installation the phone did'nt actually start. It was stuck on Booting Screen with Moto Logo.
So I again googled and started to find the solution some said restart some said remove battery some said wait I tried all but no result.
Then I tried to install the stock rom.Following this
Code:
http://androidforums.com/atrix-4g-all-things-root/510778-flashing-back-stock.html
When i start to run RSD lite it says Creating Image and then throws an error like Unable to send RAM files.
Now I want to fix my Atrix 4g and there is no backup and no recovery mod.
My fone can go into options like Fastboot and RSD Protocol Mode. I mean I can access options on pressing Power and Volume Up/Down buttons.
Can any one please tell me solution? I will be very very thankful.
In fastboot flash recovery
fastboot devices
fastboot erase recovery
fastboot falsh recovery recovery.img
fastboot reboot
Go to recovery mode, try to wipe data, cache and dalvik. If you have Neutrino rom on your internal SDcard you can flash it with recovery.

Thanks, Fortunately my senior has installed Custom rom in it. And it is working fine with custom rom.

Need help with recovery twrp

I unlocked the boot loader, then I rebooted my phone, then rebooted into recovery mode. Once I install either a custom rom, or supersu, even if it works to install, once i try to reboot, it only reboots to TWRP. Even when I reboot to system it still does that. Is my phone just bricked?

No its not bricked.. maybe soft bricked, but not bricked bricked how are you flashing recovery? are you using
fastboot flash recovery twrp.img
or
fastboot flash boot twrp.img
2nd way is incorrect. Try
fastboot flash recovery twrp.img
fastboot erase cache
then boot to twrp and flash rom and let me know what happens. Make sure you are using correct gsm twrp if you are on an att phone.
He probably followed these instructions here which direct you to flash twrp to boot instead of recovery just like you said above.
I don't know why he leaves it up there like that but seeing as it's the first link on Google when you search "root att HTC one m8" , he needs to change it cause I'm sure it's causing plenty of headaches.

I did
./fastboot flash recovery twrp.img
because I'm using mac. I didn't erase the cache though. Also on twrp, it says my phone has no os, and installing a custom rom failed to install.

[GUIDE] Restoring Stock ROM, Recovery, Unbrick, and Rooting 5.0 on Padfone S

I had stuck on ASUS logo, after I do a lot of researches, a lot of trials and errors for 4 hours. I managed to fix them and I wanted to share how I did here.
Easiest way to root lollipop WW-12.2.2.27
use KingRoot from http://www.kingroot.net/down ,It is android app which will run exploit to root the device successfully.
Not Kingoroot Kingoroot was unable to root. Towelroot v1 works only on Kitkat, but not lollipop.
To boot into fastboot mode
adb reboot bootloader
OR turn off device, press and hold power and volume up, until asus logo appear, and stuck at asus logo, that is fastboot mode, to exit fastboot with buttons, press and hold vol down and power button.
To restore stock recovery and ROM after you install TWRP or CWM, or unbrick device
First, note that stock recovery from http://forum.xda-developers.com/showpost.php?p=59055653&postcount=29, does not work for me (maybe everyone else as well).
I flashed it using fastboot flash recovery recovery.img, when I try to boot into recovery using, vol down and power, then select enter recovery, it stucks at asus logo.
First you need to flash TWRP_2.8.7.0.img from http://quarx2k.ru/asus_padfone_s/recovery/
using fastboot flash recovery TWRP_2.8.7.0.img It will show that flashing FAILED (remote: can't flash unsigned image), it fact, it was succeeded, now you can go ahead and boot to recovery.
Note that this version of TWRP, and 2.8.6.0, and CWM cannot successfully flash stock zip ROM, it may show errors, or when you try to boot the device, it will stuck at ASUS logo. But now, we are going to need TWRP_2.8.7.0 to unlock bootloader.
Let's unlock bootloader
simply flash http://quarx2k.ru/asus_padfone_s/CrowLock_RC3.zip with TWRP
You can check bootloader status with fastboot oem device-info
Before unlock :
(bootloader) Device unlocked: false
After unlock
(bootloader) Device unlocked: true
Let's flash stock Kitkat Firmware
You have to unlock bootloader becuase, well it is complicated.
The only TWRP recovery that can successfully flash stock .zip firmware from ASUS is http://datbak.com/links/padfone_s/asus_t00n_twrp_2_7_1_1.img
But this recovery has another bug, if you flash recovery and try to boot to recovery, you will get blank screen, but TWRP is indeed working, you touch the screen and it vibrates back. Anyway you have tofastboot flash recovery asus_t00n_twrp_2_7_1_1.img because it will be needed later for upgrading Kitkat to Lollipop.
If you don't unlock bootloader, you will not be able to boot into recovery directly without flashing to recovery partition Now let's get into fastboot mode, and fastboot boot asus_t00n_twrp_2_7_1_1.img, by booting into this recovery directly via fastboot without flashing it first, you will not get black screen bug of this recovery., if you boot to this recovery from recovery partition, you will get black screen as I told previously.
Now let's flash downgrade to 4.4.2 firmware from http://dlcdnet.asus.com/pub/ASUS/Mobile_Phone/PadFone_S/UL-ASUS_T00N-WW-99.99.99.0-user-wipedata.zip with TWRP 2.7.1.1.
This is for only WW SKU, not TW SKU. And all userdata will be wiped.
Browse all firmwares and there is TW SKU downgrade here : https://www.asus.com/Phone/PadFone_S_PF500KL/HelpDesk_Download/
Ok, now reboot to system, and yeah, it finally boots now.
The recovery is still TWRP, not stock one, let's upgrade to lollipop and restore stock recovery using TWRP. Simply place http://dlcdnet.asus.com/pub/ASUS/Mobile_Phone/PadFone_S/UL-ASUS_T00N-WW-12.2.2.27-user.zip to root of Internal Memory, unplug usb, press confirmation in notification to begin install lollipop. After device reboot, it will stay blank screen for 5 minutes, don't worry, it is updating to lollipop, after upgrade is done, it will reboot, and recovery will be restored to stock recovery now.
Bootloader is still unlocked.
Another method to root is
fastboot flash recovery asus_t00n_twrp_2_7_1_1.img (recovery is restored to stock now remember)
then flash https://download.chainfire.eu/696/SuperSU/UPDATE-SuperSU-v2.46.zip?retrieve_file=1 with TWRP.
To lock bootloader again, boot into fastboot
then fastboot oem reset-dev_info
But I wouldn't recommend you to lock bootloader, you will lose ability to boot to TWRP recovery without replacing stock recovery, unless you are going to send your device to service center and claim warranty.

Hi im a noob so ill get straight to the point.
You said "Note that this version of TWRP, and 2.8.6.0, and CWM cannot successfully flash stock zip ROM, it may show errors, or when you try to boot the device, it will stuck at ASUS logo."
I have two question as follow:
1. So can i use twrp to flash stock rom or not?
2. Because I'm still at Kit Kat, I dont need to unlock bootloader and flash Kit Kat firmware right?
3. If so, Can I follow the tutorial until flashing the TWRP? but which TWRP that I need to install?
4. All these tutorial to unbrick needs to be done before you brick your phone right? What should i do if i already brick my phone?
Kindly advise.

If you are bricked, but you can still access fastboot mode, then you can unbrick and reflash stock firmware to your phone
First of all, Thank you so much for this GUIDE
Here are my doubts, and hoping for confirmation from you. My Padfone S is running well on latest kitkat firmware, rooted with SuperSu and TWRP 2.7.1.1 installed. Now, I wished to upgrade to Lollipop firmware.
Can I use the TWRP 2.7.1.1 to clean install the lollipop firmware instead of the stock recovery because I wished to wipe date, cache as well as SYSTEM before flashing?
My concern is I afraid if wipe the SYSTEM then the TWRP 2.7.1.1 would not be able to flash the Lollipop firmware successfully. Do I need to unlock bootloader in my case?
If I can do so, then can I still use the Flashify to flash TWRP 2.7.1.1 on the lollipop firmware, or I must use "fastboot flash recovery TWRP_2.8.7.0.img" method.
Thanks in advance for your kindly reply.:laugh:
Bootlooped
When I am upgrading my SuperSU and it requires a reboot,it automatically boot looped itself.
What should I do?

Hi thank for your guidance on how restoring stock rom . Im having trouble detecting my phone when in fastboot mode, as you said to boot up into fastboot hold vol up and power and we will stuck at asus logo , but after i connect my pc and using adb cmd fastboot devices it didnt detect any devices and cant proceed to next step when i need to fastboot boot twrp 2.7.1.1
Currently im using twrp 2.8.7.0 , i want to use stockcrom because i need to use my padfone station (since any custom rom is not compatible with padfone station), any suggestions for this problem ? Thanks in advabce

Tried flashing TWRP, but stays stuck on/replace by stock recovery no matter what Itry

No matter how I try to flash the TWRP recovery image to the recovery partition, TWRP gets replaced by the crappy stock recovery!! This is absolutely maddening!
Specifically, it seems that no matter what method to use to flash the TWRP recovery, it gets overriden by the stock loader when the phone reboots.
My bootloader is UNLOCKED and I've installed a custom rom just fine by using the command fastboot boot twrp.img to boot into the twrp image. This is the only way I'm able to use TWRP at all.
I've tried:
fastboot flash recovery twrp.img
Booting into TWRP, and flashing the image over the recovery partition
Flashify to flash the TWRP over the recovery partition from within the rom
Trying to flash cyangenmod's recovery from within the rom (was pretty desperate at this point..)
I've also tried many different versions of TWRP, I can boot into them just fine but none of them stick when I flash them to the recovery partition.
It always says it's successful when I try to flash it, I reboot into recovery, and it boots into the piece of crap EmUI stock recovery screen every time
Anyone have any pointers here? It's not the end of the world but it's pretty aggravating having a completely useless recovery if I'm not near a computer,.
Try using Flashify or Flashfire.
Sadly didn't work. It doesn't seem to matter how I flash the recovery, the bootloader replaces it with the stock recovery when it boots. I'll update the OP to clarify, but thank you
I am having same issue have you found a fix
Have you tried starting completely over? Like, downloading the official MM build (b331, C564D003) from Huawei (Assuming you're on L24)?
On the new, freshly installed ROM, make sure that USB Debugging is and enable OEM Unlock are on in the developer settings.
Then, try flashing this build of TWRP again.
Before rebooting, do a Cache/Dalvik Wipe.
Boot up into the stock rom, then use 'adb reboot recovery' to see what happens next. It should work...
Hi mate,
It'd be easier to help you if you could post a screenshot of your FASTBOOT screen. There will be a line that will say FRP=LOCKED/UNLOCKED something like this.
if it is locked,
you have to install stock rom & enable OEM unlock from setting.
Then relock the boot loader. Then again unlock the boot loader.
For myself, I unlocked my BL unofficially, & this problem occurred . I solved it this way...
Hope it helps.
Cheers!
