Hello navroza
please do read more threads about your phone here on XDA. there are always phone-relatet special ways to unlock bootloaders and to modify your phone in the correct way. to do that there is build special software that only works for your phone. You can damage your phone instantly if you use any other software of recovery- or bootimages that is not made for your phone.
Hello all,
yesterday's OTA firmware update to my CAT B15Q (CPU MediaTek MT6582M) showed an error similar to "failed to update metadata symlink" and offered me to reboot... since then the device is stuck in a bootloop and only boots recovery and fastboot.
The recovery console doesn't offer any USB devices, except when choosing "apply update from ADB", upon which adb devices lists it as "0123456789ABCDEF sideload". adb shell however does not work, it gives an "error: closed" message.
Resetting to factory did not help either, current Android version of the device was 4.4.2.
By the looks, the failed update bricked the /system somehow; can I sideload a version of adb onto the recovery to gain shell access?
Thanks!

Can you elaborate?
Do you hold before and while turning on?
Did you hold with the battery Out with charger?
I tried to hold while booting but it just stays in the inicial image forever.

Ha, same for me. Even adb comes halfway up (adb device shows up in windows' device manager, but "unauthorized", so no shell/pull/push), but it doesn't progress beyond the loading image.
Can anyone with a working B15Q please execute the command "cat /proc/mtd" in a shell or do a full(!) backup using mtkdroidtool?! I pledge €20 via Paypal to the first one who submits all of the partitions except /data up to Mega or another OCH.

My phone bricked after updating to 1.1019.000
I was lucky enough to save the whole ROM to a file before updating.
The problem for me was the original recovery.
My solution was to install the new 1.1019.000 recovery on my original ROM and then updated to the new (1.1019.000) firmware.
Give me your mail and i will send you the 1.1019.000 recovery. I have the whole ROM but it´s to large and i am to lazy to upload

Another one here! Were you able to use link2sd after rooting the phone? Link2sd gave me a mount error when I tried to mount my sd card's 2nd ext3 partition.
Many ppl wanted the stock rom. So i uploaded it to my google drive. It´s a E01 so beware those of you who has B01 or something else.
Original 1.1010.000 rom in files with scatterfile

Thank you very much - but how can I determine if my phone is E01/B01 without being able to boot it?
So, I can confirm that reflashing your ANDROID/RECOVERY/BOOTIMG unbricked my European B15Q!

Can you give some hints how you unbricked it? What tools and commands have to be entered?
Best regards,

Uploads are not done yet. But you can prepare until I'm done... grab the driver package, spFlashTool and the 1.022 RAR from http://forum.xda-developers.com/general/general/stock-rom-cat-b15q-rom-development-t2988774.
You will need a win7 x86 machine for this to work (64-bit systems will need to disable the driver signature enforcement, but this is unreliable), and latest(!) WinRAR for unpacking.
The full backup of your device will take up ~1.5 GB, so you will need at least 3GB free and another 2GB if you also want to backup your userdata (HIGHLY RECOMMENDED).
"PMT changed for the ROM; it must be downloaded"
I'm trying to flash the files of harddisk_wp with his instructions but i keep getting the error "PMT changed for the ROM; it must be downloaded", right after I connect the phone and SP Flash Tool finishes "Download DA". I am trying with the 64bit drivers since I do not have a 32bit system, with digital signature verification disabled.
After some search, I saw in the log files that SP Flash Tool is reading the partition table on the phone and comparing it to the scatter file. There is a mismatch there and throws this exception. Now either the driver is not working correct and does not report the partition table right or there is something else going on. Anybody tried this on a 64bit system? Any ideas?
BTW the scatter file is correct for my phone. I had downloaded it myself also before the bricking and I compared it with harddisk_wp's one. They are identical.
In all other aspects SP Flash Tool works fine, I read the user partition for backup without problems.

SPFT worked for me good to resurrect the phone with files from 1010 version (first firmware) raw partitions.
Phone came back to last user backup and booted fine.
I applied newer and suggested 1019 update that had bricked the phone even further into the loop of the booting logo stuck and rebooting.
SPFT tool memory scan showed that there is no NAND present. I assume that there is PRELOADER damaged. By trying to flush raw PRELOADER that was a no go area. Connection made red line on 100% and nothing happens after that.
SPFT stopped making connection via USB. Inserting the battery, power on - it didn't came back at all.
Phone is now dead black brick that on Linux shows: as MediaTek Inc. MT6227 phone.
In any case do not try to make the same mistake like me.
I will check if it works on some other Windows machine.
Not being Windows user I cannot tell if it is in USB driver or not.
Used W7 without admin pass, with MTKUsbAll driver.
Eh.
Hi
I have Coolpad E501 EU (other names: Modena, Y76, Sky). It's dual sim, stock android 5.1, rooted, stock recovery.
After last mini update (9,2 MB) coolpad logo is showing and then it goes only to recovery. Phone was rooted using KingRoot app, and then applied update so I bet it was a mistake to do so.
I have second one same Coolpad phone - working, rooted, stock android, stock recovery. So it might help in restoring bricked one.
I searched almost everywhere on the internet looking for stock roms, recovery or something that I can flash.
I tried using YGDP tool with 4.4 official rom that I found but no luck. I get the message "Bootloader is old" in logs.
Tried to do backup with nandroid of working phone but it's making backup for custom recovery (cwm - .tar or twrp - .wim). My phone doesn't have one.
Recovery has an option to apply update from zip. Last update that messed up is here:
ota.coolyun.com/ota/Android/Coolpad%20E501_EU/P0/5.1.222.51.P0.151216.Y76_U00_5.1.222.61.P0.160510.Y76_U00/update_1464055522221.zip
I dont care about data., only working system.
Anyway I appreciate some help how to bite that, any ideas how to revive that phone. I was trying to do a system.img backup of /system partition in working phone, but no luck, partition is in ext4. I thought I can restore that using adb.
I will answer any questions if something I wrote is not clear. I'm not afraid of adb, flashed many phones, so I'm not looking for step by step tutorial, only to someone point me in right direction to solve this problem
Thanks for any help.

I found some custom roms and some software on chinese site, but cant flash them and I think it's because bootloader isn't unlocked. I tried unlocking it but no luck (using android sdk).

I have twrp for this phone, but I cant flash it. Every time I try to send a command in fastboot mode I get the message: "FAILED (remote: unknown command)". How did you flash it? Did your bootloader was unlocked in developer settings? Mine wasn't so I think I'm screwed.
Backup I have is with my personal data.

Hello ppl!
Is yours problems solved? I have soft bricked Coolpad Modena E501_EU and can't find solution.
Searching everywhere on internet, not find nothing about that phone: kernels, drivers, firmwares etc., like "ghost phone". Firmware version 4.4 is for E501-Y76-Sky but not for EU model and cannot be flashed. I need stock 5.1.222.........Y76_U00 and if can someone make backup and upload somewhere he helped me a lot.
I've downloaded the stock ROM from the acer site, put it on my SD card and went into recovery to apply the update from the sdcard. When trying to update I got the following error:
e: footer is wrong
e: signature verification failed
Installation aborted.
Now, I've searched everywhere and tried at least 20 different things without anything working. I've unlocked the bootloader and flashed the boot.img which was inside the update file I downloaded from the acer site, I've tried flashing certain files seperatly etc. Another problem is, there is no system.img or recovery.img or any other img file in the stock rom from acer which doesn't allow me to flash it via the fastboot. So either I need to find those img files, or I need a fix for the error above.
Any suggestions?
(One more thing, I really can't try using a custom recovery to disable signature verification because the Liquid Z330 is such an unsupported phone, there is no cwm or twrp recovery for it. I also don't wanna risk trying another phone's cwm or twrp on the Z330 because I don't have the stock recovery.img file in case it doesn't work.)
UPDATE: I found an older version of twrp for the phone and I was able to disable signature verification but when trying to install the zip I get this error log:
Updating partition details...
*in red* E: Unable to mount '/system'
...done
Full SELinux support is present.
MTP Enabled
Installing '/sdcard/update.zip'...
Checking for MD5 file...
Skipping MD5 check: no MD5 file found
Error flashing zip '/sdcard/update.zip'
Any new suggestions as to what might be the problem?
Update2:
So after Ysfzone posted this tutorial:
http://forum.xda-developers.com/general/general/acer-liquid-z330-unbrick-unlock-t3520952
I was able to restore my acer liquid z330.
I did actually run into some trouble with Ysfzone's instructions, and found a way around it, it should be the second comment on the post.
My only problem now is that the system is restored it's booting into demo mode. When I try to update it downloads the update and reboots into TWRP and when I then reboot to the system it says that the install failed. I think it would automatically install the update with the stock recovery but because I have TWRP installed I have to find the downloaded update file and install it manually.
So I have two options:
Either someone tells me where the update download folder is, or someone provides me with the stock recovery.
Any help?
Exactly same issues
Hey there!
I have the exact same issues. I have been trying to unbrick my phone, but nothing has actually worked. My phone is still stuck on the white screen with the acer logo.
Did you make any progress?
Were you able to find out anything that works??
Any help will be appreciated.
Thanks

(If you don't want to read the story, read the last sentence.)
I actually was able to get rid of the MD5 check error by creating a MD5 file myself. You basically have to download an application that gets you the MD5 sum. I used this: http://www.fast-files.com/getfile.aspx?file=127067 (just reuploaded it because I forgot where I got it from). Using the exe file in there I generated the MD5 file in this format: d2a862b7c1a8f66b6d1be32f400dc73e *update.zip. After that I tried installing the zip again, this time I got the same error except with the MD5 error missing. After contacting Acer support, I was basically told that I needed to send my info back so I could get contacted for a repair. But since I flashed the recovery it probably wouldn't fall under warranty.
So basically try emailing Acer support and try and get them to repair it. I havent found a way to fix it myself.
One more thing. It wasn't my phone to begin with, I just tried to fix it for someone. That person already has a new phone and I won't be trying anything anymore to fix the phone since I don't have it anymore.
Hello everyone,
I've been in the same situation as you until few hours.
I've also tried a lot of things which doesn't work at all ( like extracting system.img from the Acer update.zip ).
I've seen that every time I tried to install an update.zip package I get the same error:
E: footer is wrong.
E: signature verification failed
And I solved it by unzipping and zipping it again.
Then when I was able to flash it and get my phone back.
if it still doesn't work with the stock recovery, you may try with a custom recovery ( like twrp, you can easily find it on google )
If you have any questions about it, I can try to answer them.
Hope it'll help !

Thanks for the suggestion. Just out of curiousity I guess I'll ask the phone back and try it.
I've tried it again, but the problem isn't because the signature verification fails, its something else. Idk what.
Hello Mounir9912,
Have you try to re-download the file from acer website, or/and to check the zip file with winzip or winrar ?
I've read that you created a md5 file, for my part I just disable md5 verification from TWRP.
It seems like you've got a system mount error, do you still get it if you wipe all partition on your phone (system, cache, data, dalvik cache) ?
Finally, I don't know if it can be useful, but I have a TWRP backup of my z330
I'll stay available if you still have trouble.

You might just be the godsend I needed. I've already tried everything you said including wiping and disabling the verification. Could you upload the twrp backup somewhere? It might be the only thing that can save this phone aside from paying way too much money to acer because of a voided warrantee.

damn, mega is being an asshole. I downloaded it but while downloading I accidentally unplugged the power cable from my laptop and it shut down so I had to redownload. When I downloaded again it cut me off at like 90% because of exceeding the bandwidth quota of 5GB. Now I have to either pay a monthly fee or wait 5 hours...
Hey pixie,
I've actually restored it via twrp, but it still isn't booting past the logo. Could you maybe make a backup of all the partitions except the boot, system and data partitions? The problem is probably in one of those partitions since restoring the boot or system didn't fix it.
more specifically, the ones I could backup are:
Modem, Aboot, pad, modemst1, modemst2, misc, splash, fsg, persist, cache, devinfo, oem

Sorry for my bad english

hello,
first sorry for the delay.
As far as i remember, I've checked all when I backup the phone. But all that things you list are not unknown, I've seen them when the phone was still bricked. By the way, I even made a backup at this moment, so if you think that it can be useful..
Ysfzone, have you try to use qfil to get you're stock recovery ?
Hello XDA!
I am writing this thread to ask for help rooting my Samsung Galaxy J2 Pro.
I attempted to use apps such as: Framaroot, Kingroot, etc.. but so far none of them have worked and I have not been able to find a working guide on the internet of how to root my phone.
I also tried installing an unofficial version of TWRP for my phone but everytime I tried to boot into the recovery it would say "No Command" and then boot into the original recovery.
Is anyone able to help me root my phone? Can it even be done?
Any help is sincerely appreciated. Thanks!

Try this at your own risk
Make a backup before trying
I got root access with this method
Download stock Rom from sammobile extract and there should be 5 MD5 files extract the AP file with 7z and copied boot.img on to sdcard
Installed MagicalMmanager-7 used it to patch the boot.img to a tar file
Copied the boot image to my pc desktop then flashed the boot with odin
When I booted it back up magisk manager kept crashing so I uninstalled it and installed magiskmanager-5.23 rebooted it opened magisk and followed the prompts to update it

Hello there.
I have tried to patch my boot.img but when I put into a .tar and flash it, it doesn't flash, it's just stuck on file analysis despite being able to flash other files. Would you be able to send me a copy of your boot.img, thanks.

I attempted to use apps such as: Framaroot, Kingroot, etc.. but so far none of them have worked and I have not been able to find a working guide on the internet of how to root my phone.
I also tried installing an unofficial version of TWRP for my phone but everytime I tried to boot into the recovery it would say "No Command" and then boot into the original recovery.
Is anyone able to help me root my phone? Can it even be done?
Any help is sincerely appreciated. Thanks!
Phone Specifications:
Samsung Galaxy J2 Pro.
SM-J250G
Android Version: 7.1.1

Unfortunately I have not found a solution. Please notify me if you find one.
here is a copy of my boot.img after flashing this you will get a verification problem and you will have to reset your phone if it bootloops into recovery or starts to update and says no command take battery out put it back in and boot it again or boot in to odin mode and push down and boot it eventually it will boot in to recovery then factory reset it. first boot may take 5-10 minutes
my software version is J250GDXU2ARD3_J250GXSA2ARD3_XSA

Hello and thanks a lot! I flashed my boot image and now when it boots it says "Set Warranty Bit : Kernel" and an infinite booting screen.
What do I do from here? or do I need to flash the original rom?
don't worry about "Set Warranty Bit : Kernel" mine does it too here is another boot.img after i flashed this i got verification failed so i used 7z to tar userdata.img.ext4 i extracted from the AP image i got the boot.img from.
i put boot in BL and userdata in AP and flashed it. it fired up as normal and then i installed magisk apk

Hey, sorry for the late response. Everything is working fine! I now have superuser abilities but everytime I try to flash my recovery with TWRP it just loads the stock recovery. I even tried removing certain files from the root folder to avoid the stock recovery being flashed but it hasn't worked.
Any idea? Ps. You are a life saver my man.

glad i could help and i don't think there is an official twrp for this device here is one i ported a couple things still don't work mtp and sideload but it's not really usable until someone ports a rom due to the data encryption which you have to format to be able to flash anything

Hello,
Sorry, I don't have the J250G anymore as I traded it for a J5.
Kindest Regards
Jayden
My internal storage showed I only have 8gb instead of 16gb. Is there a fix for this?
P.S. Wiping data fixes it
ok
You can extract it from the AP file from stock firmware using 7z
hey
hey everyone im just wondering but is there a kernel for this device yet or any rom ("J250G")
