Bricked? target reported max download size of 536870912 bytes

[Solved]Dear friends,
I tried to upgrade my Nexus 5x via factory image files and adb commands. FYI I have done it before on my Nexus 4 so I thought it would be straightforward.
Downloaded the image files and did as the routine procedure is. However when I was flashing individual files, it was system.img turn to be flashed, I got this error "target reported max download size of 536870912 bytes"
and it won't flash system.img file.
The phone can go into bootloader, but fails to start up or whatever.
Any solution is much appreciated. :crying:
[emoji736] Solution:
Use flashall.bat which comes with the stock recovery and give it a good deal of time to parse system.img and transfer it to the phone.

You have to wait longer.

sure thet you have flashed img files one by one? i've had the same problem flashing factory image by flashall.bat...flashing img file one by one, no prob.
but if you have this problem with manual flash, try to flash twrp and install a rom zip by twrp

It isn't an error I think.
it's because the filesize of system.img is too big for flashed in one go, so system.img need to be parsed (in Nougat, it become 5 parts) and send one by one to phone (the fastboot command will handle this, so no need to manual parsing).
I had this problem, I just canceled the command and tried again, and success.
if it still not working, try clear cache and reset from recovery (twrp is recommended)
as long as your phone can boot to bootloader and detected by fastboot, I think your phone is far from bricked.

I am on stock recovery.
I managed to solve the problem by using "flash all" command instead of flashing each file separately.
Thanks for the reply though.

There might have been a problem with the version of fastboot I was using since it was unable to parse the package automatically and I had to use flashall.bat and give it a good deal of time to be parsed, transfered and written.

Glad that you figured it out. Make sure to update your fastboot of course. For me, flashing system.img took quite awhile longer than I recall it taking on Marshmallow but it did eventually flash for me.

It's confirmed, need updating fastboot to latest version to get it work.

Thanks. I figured it out accidentally by leaving the phone connected for a while and saw it booted up and all done with flashing.

My phone is the ASUS Zenfone 3 deluxe (zs550kl) model and its bricked only can enter fastboot or adb still but my os will not boot I tried going to asus website for stock firmware (UL-Z018-WW-11.40.71.37-user.zip) and stock kernel (ZS550KL_Kermel_11_40_71_37.zip). how do I install these to fix my phone unless there is a better way to make it boot. by the way im new to android I always had iphone jailbroken until last year I am android now but give me noob instructions for the how to. maybe I should add this I already have adb/fastboot installed and the commands for adb devices or fastboot devices when in fastboot mode both recognize my device so maybe my commands are wrong or something but I tried every way I could toinstill firmware and not sure what to flash kernel as the zip or the file unzipped please help thanks in advance. Not sure why this happened exactly but my bootloader is unlocked already but was never rooted so if there is another way to install another custom firmware besides stock I would like those instructions also thanks again

first off your phone is soft brick meaning all you have to do is flash the stock android software back onto your phone.
install to sd card -> boot into recovery (stock or twrp whatever you have works)
flash from sd
let it load (this will work if you have the correct files)
it will reboot and will work good as new again.
you shouldnt have to flash the kernal, just the UL-Z0 file.

That would have worked yesterday but im having another issue now basically instead of waiting for a response on here I went ahead and did other stuff now my recovery menu is not showing up so I cant install from sd now the only option I'm getting is fastboot so is there a way to fix the stock recovery option or even install a custom recovery which might be eaiser because my bootloader is already unlocked. I was going to try to flash stock recovery my self but not sure how exactly I know I use fastboot flash recovery (recovery file name in the folder) and I think it's .img but not sure so I think it will be either .zip or .img file type but not sure what it will be called if it's stock or custom and not sure where to find either. Last issue I'm not sure of is the actual files I downloaded from asus.com the firmware for my specific phone model not working when I try to flash it as the .zip file so my question is do you need to do something with it such as edit the script of something inside the zip of it and I also downloaded the kernel for my specific phone model from the Asus site and not sure if I needed it when flashing stock rom back to device or how to even flash it on the device please help if you can and I know some questions might be dumb to you but remember I'm a noob when it comes to Android recently left iPhone and I was a pro there every phone had a jailbreak and all types of stuff so I know I can get this just takes time I'm sure

I have this exact issue with a new Padfone Infinity A86... No access to stock recovery, only fast boot... But in my case I'm even unable to flash the recovery.img from a firmware package...
I'm wondering if you guys can help this person, maybe there is something in that solution for my Padfone

1: download the full firmware package
2: use sdat2img to convert the sparse system image to a regular one
3: use fastboot to flash the stock boot.img & the newly converted system.img
4: hoping you didn't flash the recovery partition, if you did, reflash the stock dump from the file in my Bootloader unlock thread via fastboot
5: reboot to recovery & do a factory reset
Read the documentation at each step, do your research, learn the process.

Doing the update second time is fine, and best way to restore full stock. But you needed to use Oreo version of no-check recovery and the Oreo partition to flash it to.
So if still able to get into twrp, can try with correct no-check recovery and correct partition it's flashed to.
Also
With multi tool , make sure you put check mark on emui 8. Up in upper right corner. That way it uses Oreo partition names and file not nougat.
The partition length over message usually means nougat file or partition name used on Oreo system

On the extractor app. On options tab uncheck the verify header option, it should extract then.
Then perhaps first do these three partitions.
Kernel.img
Ramdisk.img
Then
twrp_ramdisk or for stock use recovery_ramdisk

I ever have similiar problem with you dude, but it's solved now, if you always stuck on " its OK but when my phone want to start its stuck on google page "just a sec...", its call google accont verification, i'll by bypass with this script, save as to .bat and put on adb folder
adb devices
adb shell content insert --uri content://settings/secure --bind name:s:user_setup_complete --bind value:s:1
adb shell am start -n com.google.android.gsf.login/
adb shell am start -n com.google.android.gsf.login.LoginActivity
pause
in fastboot type:
fastboot -w
after all it's works to me to bypass google account verification
and if now your problem is

So now is locked frp. Does phone have twrp or stock now.?
I think when you tried to install the oreo update for second time, you followed same tutorial as the first time. And that made you problem worse. The tutorial has you flash no-check recovery to 2 partition by block number. 22 & 29. On nougat that is "recovery" and "recovery2". On Oreo partion table it is "reserved2" & "erecovery_vendor"
I don't know how to fix imei. Have hope that if to ucan have a full ota install , maybe can be fixed.
There is available a "service rom" (used to fix most all problem) for Europe region with l21.
I can share link to site with service rom if you want , but I have not used it myself so not gonna be much help with it.
Link is to rusian language page. Google should translate for you.

in summery. because i have been going back and forth in multiple different groups, multiple problem, i cant remember it all.
you have broken system, from failed root attempt, followed by failed update.
device condition is as follows.
--system not booting
--stock recovery loads
--fastboot/bootloader loads, but is in frp lock status
options are limited, at best.
I think "dload" method with service rom is best.
other option is maybe paid service like dc-unlock. But I can recall some note on there service about frp-unlock, that can only be used on device with working system. (of course if was working system, wouldn't need dc-unlock)

what about the "about phone" screen
what does it show for version?
If is all stock you should be able to go into deveolper options and enable "oem unlock". If it is greyed out and cannot switch it. Try First to remove google account (all accounts ). and reboot. See if can change then. If not, try Second to do "fastboot oem relock [enter your bootloader code here]
after relock and rebooted oem switch should be enabled again.
****RELOCK IS ONLY ADVISED IF 100% STOCK ROM****
otherwise relock could make more trouble.
Still not sure how to get IMEI back even if unlocked frp though.
**And please stop posting in other threads , the same problem , because you are getting help here.
your post in recovery thread is off topic to that thread and just makes the forum harder to maintain.

Hello I have a Huawei Mate-SE (with bootloader unlocked and rooted with magisk v16). I have been using the android custom rom RRO v6 (RR-O-v6.0.0-20180401-bnd-OpenKirin) for around a month now. I got this exact same problem about the White Screen saying "ERROR MODE Attention...." since I updated the Magisk to latest version (from the installed application) and rebooted my phone. SInce I rebooted I am getting that same error which makes the phone loops into it for a few times and then it loads the Huawei eRecovery that offers me some options that I am not sure what would do to my phone.
I have been trying to connect to adb tools/fastboot but it doesn't detect the phone and im pretty sure I have the device drivers installed on my computer since nothing have changed in my pc for a month now since I flashed RRO on it.
Is there any other mode besides recovery that would allow me to connect adb/fastboot to it? Or does anyone knows how should I proceed?

I have seen where the magisk update screwed up and patches the kernel intead of the ramdisk.
Power off , long press power button.
Hold volume down and plug in USB from PC.
This should cause it to boot into fastboot mode.
Then flash the stock kernel. And the stock or first patched ramdisk. (From earlier root)

Hi thank you I was able to finally detect the device now. I am unsure about the kernel is that the recovery.img or system.img files I downloaded (i saved every file i used when I installed the rom) or do I need to look for the kernel somewhere else? I do have the complete_twrp_ramdisk.img file though.
Edit, I did more research and found the stock kernel is withing the boot.img file which I dont have so I looked up for the official BND-L34 oreo update and im currently downloading to extract the stock boot.img from the update.zip and flash it. Since that download was going to take me a while anyway i tried flashing the twrp recovery file without success (didn't changed anything) so i guess I should follow the instructions you gave me by flashing the kernel first then the twrp recovery.

if you were on oreo. then there is not a boot.img, instaed there is seperate ramdisk.img and kernel.img.
i have all the files already extracted for oreo and a backup from nougat as well.
https://androidfilehost.com/?w=files&flid=265998
make sure you know what you are doing before flashing.
for example. on oreo the boot and recovery share one kernel image. SO if kernel is messed up you will not be able to boot "boot" or "recovery"

Red Magic 5G BackUP Request

Hello XDA Forum
I have a little problem with my Red Magic 5G
I accidentally deleted the parameter files and also other important files out of stupidity and wanted to ask whether someone has a red magic 5g and can make a backup via twrp and send it to me? < I really don't know what to do anymore >
I have flashed new software with edl on it and installed all 3 rom versions but I still have the same problem non of them worked i can't even install custom rom anymore.
Best Regards
Akizuma

Has really no one a backup for me left for the red magic 5g ?

Hello, what parameters are missing in your red magic5g, can I help you? I use red magic5s

(I think everthing)
I need a twrp backup from a red magic 5g where everthing still works i destroyed to much,
Not even touch working anymore in twrp.
Edit ( I think not that 5s works on 5g or ? )

you don't need anything from someone else's device.
if you ****ed something up. then you need to use the unbrick tools. and set them up correctly and follow the directions to unbrick.
they will erase all your data. but form what I've read, you lost all that already.
there are unbrick tools for both devices. 5S or 5G on either forum for those devices make sure you're using the correct unbrick tool. 5g does not work correctly with 5S devices, and vice versa.
the unbrick tools will format and restore every single parition on the phone. restoring it to factory settings.
its very possible though if you were messing with partitions that you erased your IMEI.
if thats gone, its beyond the scope of the unbrick tools. you'll have to contact warranty services.
the unnofficial unbrick tools by Johnny in my opinion better.
just make sure your drivers are correctly installed, and up to date. .. this includes windows updates.
(recently there has been a google ADB driver that needs updating thats available through winodws update)
so make sure thats installed too.
set your phone to EDL mode and follow the direction on Johnny's thread.
it will restore your phone as long as you can get to Fastboot mode. (vol down and power)
PM me if you need more help. but that should be enough to get your back to stock.

[Tool] Nubia Red Magic 5G Unbirck Tool
So.......It's finally here, the unbrick tool for RedMagic 5G. This tool can help you to unbrick the phone. It will restore the phone to the oldest version, you need to update the system software by yourself. This tool is based on Qualcomm...
forum.xda-developers.com
Then follow the instructions in the folder and install an operating system on it through edl mode
Then you start the installation again but this time you don't run it because I noticed that the tool doesn't flash important image files but skips them (you can even find it in the log)
First go to \ AppData \ Local \ Temp \ is-K4OSH.tmp \ NubiaEmergencyDownload \ software
(name can be different)
And copy
persist.img
boot.img
odm.img
recovery.img
system.img
vendor.img
And put it in a new folder
After that go to the bootloader again and unlock the oem via
(fastboot oem nubia_unlock NUBIA_NX659J)
Then execute following commands for the files like
(Command (Fastboot flash persist [file.img])
(Command (Fastboot flash boot [file.img])
(Command (Fastboot flash odm [file.img])
(Command (Fastboot flash recovery [file.img])
(Command (Fastboot flash system [file.img])
(Command (Fastboot flash vendor [file.img])
It can be that most of them give out an error, execute them anyway in case the folder still exists
Then the cell phone should start again normally.
P.s ( Sorry for my poor english ^^ )

System, Vendor, and odm, are all partitions flashed during the "super" partition.
this is why you didn't see them exactly written in the log they all go under "super" and get assigned a dynamic partition when flashed.
you cna see here how they changed the partitions and how they're written now.

either way. thank you for your effort to your solution.

Fastboot Loop

Hey guys,
I'm currently stuck in a fastboot loop after trying to install Magisk after flashing the Arrow ROM. I believe I messed up when choosing between boot_a and boot_b and flashing the patched img via QFIL. I initally patched boot_a, but when that didn't work I rebooted and patched boot_b. I did this because when I installed Arrow the instructions asked me to select the device slot that was inactive. I thought this meant it was swapping my device slot from A to B, but I probably got that very wrong. I did go into EDL mode and flash my original boot_a and boot_b in hopes it would reverse my mistake, but that did not work.
When I attempt booting the TWRP zip from the lineage guide archive I get this error "failed to load/authenticate boot image". I'm assuming this is because it wants an .img file and not a zip. If I try flashing the same zip file I get this error "Cannot flash this partition in unlocked state".
I did make a backup of all partitions via TWRP before this, but I'm unsure how I'd go about restoring everything. I do have access to EDL mode.
Any help is appreciated. This isn't a primary device though, so if it's bricked I'm not going to be that upset over it. Just something I wanted to try for fun. Haven't rooted a device in years. The G8 was a bit more difficult than I recall, so I'm sure I made a mistake somewhere.
Update 1
I flashed the ABL enginnering file and have some progress. Now fastboot shows my Active A/B Slot. It is set to B now, it was A originally, which I guess confirms that the Arrow OS instructions did switch from A to B. Maybe patching both through Magisk broke the boot image? If I'm understanding this correctly.
Update 2
While in fastboot (Phone was still looping) I entered the following command to change from Active Slot B to A, "fastboot --set-active=a". I've read this could potentially brick your device, but since my device was originally set to A and it was a brick at the moment already I took the risk. Booted into the recovery mode and selected factory reset. It took about five minutes, but I'm now back to the setup screen in the OS. Glad to be back to this point. Now I just need to figure out how to get Magisk Root working without repeating this process.
Update 3
Almost forgot to boot back into EDL, load up QFIL and push the original abl_a and abl_b files back to your phone. Otherwise you won't have any touch input.
Update 4
I seemed to have messed it up again. I tried locking the bootloader back, so I'd stop getting the error message upon bootup. I've decided there is no benefit to unlocking the bootloader and rooting for my purposes. Just wanted to try it out. After doing so I started getting an error stating the device failed security checks, so I pushed the abl engineering file back to the device to unlock it. After I went to push the stock abl_a and b files and decided to go ahead and push the stock boot_a and boot_b to make sure everything was back to normal. Which I didn't think was a big deal, but now I can't boot into the phone without using the abl engineering file.
At the moment I'm unsure what to do. If I push the abl_a and b stock files the phone goes into a fastboot bootloop again. Can't run any commands that way either. I have to boot the abl enginnering file to do so, which in turn allows me to get into the OS but disables touch input. So at the moment I think it's bricked.
If I could find a TWRP image file to flash with the abl enginnering file I could possibly perform a restore from the original backups I made, but I'm unsure where to find one since TWRP doesn't really exist for the G8. I just have a zip file.
Overall not too much of a loss, but the G8 was a great DAP. Hate to lose it. If anyone has any suggestions I'm all ears.

Absolutely the same issue. I wrote about it in arrowOS thread . But I did not try to flash engineering abl. I'm begging you, if your will find solution, please write here about it. I am also notice you here, if resolve this issue.

It's a little confusing to try to determine where you are with this, but I can tell you that for the G8, to get twrp 'injected' into the boot partition, you use magisk and flash the zip, you don't 'boot' it.
So to accomplish that, you need **your specific variant** boot partition with magisk injected into it. You can do that yourself by using the magisk manager, or by simply asking if anyone has that available.
But, you'd then have twrp, and you could flash backups, but, from what you say, it's hard to determine if that's going to help.
If you have one of the variants that has the kdz available, I'd suggest simply use LGUP and flash your kdz, and start from scratch.
Lastly, re locking the bootloader. Numerous people make this mistake, but you can't re-lock it unless you're on pure stock (no modifications at all). If you try to re-lock it and yer not on a freshly flashed stock kdz, you can end with 'edl mode only' device.
cheers

As of right now I have a kdz for my phone, I have a Verizon model. Where I'm having trouble with now is I can't get the phone into Download mode. When I do it says my device failed a routine safety check and then boots to fastboot mode.
I also have a couple patched magisk boot partitions from the initial install. I loaded them via QFIL and I can now get to the Verizon bootup screen, but it gets stuck in a loop.
Update:
I got into Download mode by going into the system recovery and doing a factory reset. Now I need to figure out LG UP.
Last Update (Hopefully) Lol:
I installed the kdz using LGUP and it seems to have worked! I'm back in the stock OS and touch input is working. I'm relieved. I hate leaving things like this in a broken state if it's possible to fix it.
Thank you @AsItLies for responding and helping out!

What I did was put the phone back into EDL mode and open QFIL. I loaded my original magisk patched .img file. This got me out of the Fastboot loop. Then after holding volume down and power to reset the phone out of EDL mode I pressed volume down and power again to boot into the modified system recovery. This took a few attempts as it's really finicky.
Once I was in the modified system recovery I performed a factory reset. This seems to have resolved my "Failed routine security check" error when trying to access Download mode. Now that I was no longer getting that error I booted backup into the modified system recovery and hit power down. Make sure your phone is not plugged into your PC at this time or else it will just boot back up.
Once your phone is off and unplugged, hold volume up and then plug the phone back into the PC. Hold volume up until download mode starts. Now you can go go about installing the kdz of your phone.
Now I'm not sure what model your phone is, but since mine was Verizon I found a Verizon KDZ. Then downloaded LGUP. There are a lot of different variations of LGUP, but for my G8 I needed at least 1.16. So I download the Lab version (Probably not right. It scaled very small, but hey, it worked).
You also need to download the DLL for your phone and place it in your Program FIles (x86)/LG Electronics/LG UP/Model/Common folder. I did have to create the Common folder for some reason, but after I did everything worked fine. Make sure to rename the DLL "lgup_common" (without quotes).
You'll also need the LG Drivers for your phone as well, if you haven't installed them already.
I'll post a couple links for you below of where I got this information or files from. I hope this all helps. If you have any questions just let me know. I'm no expert, but I'll do my best to help.

Woo, thats great, that you resolve your problem! I will try to do all like in your manual.
imei.guru said, that for my imei i have :
Model: LGABCD
Region: ABC
LG LMG820N
With such region i did not find kdz at lg-firmwares.com
When my smartphone boot up (when it was worked) i see LG U+ when booting.
Also it was trying to set korean language. What do you think, which kdz should I take? And what version of android?

also solved my problems - here i described here how https://forum.xda-developers.com/t/...lg-g8-alphaplus-alphalm.4354847/post-86038237

Can you share the LGUP 1.16 that worked for you. The link you provided has LGUP 1.16 [Orignal from LG] – No patched – Lab Version and that does not work or not even opening after installation. Thanks.

I just tried installing it from scratch and other than it asking for the LG driver it launched on my end. Are you going into your start menu and opening LGUP?

I find out that Windows 11 is the problem. Something to do with stupid driver signature. Used Windows 10 and that worked. Thanks.
