i was trying to dload mm firmware. The firmware dloaded fine but after factory reset and reboot, the fone is jus staying on honor screen after 3d text. i tried to go in erecovery but cannot, fone jus vibrates twice and then after 3d honor text, it stays on blue honor screen forever.
i tried to boot in fastboot as well as dload.....same thing happend not booting in fastboot or dload.
only 3d text and blue screen.
now fone doesnt even turns on if power button pressed ,but juss vibrates twice and blue screen after 3d text.

Leave your device as it is so that the battery is fully drained and is powered off. Then plug your device to charger for 5 minutes. Unplug it and now try to boot to recovery.
Hold the power button and volume up button until you hear the first vibration and screen goes on. Leave both buttons. Now you can go to recovery. Perform a full factory reset. Then power off your device and move the dload package to your external SD card. Repeat the same process but this time hold both volume buttons and power button.

thankyou bro for ur suggestion...i already tried all tht but no luck.
the fone turns on everytime whatever i try to do....only 3d text and it is stuck on blue honor screen.
no recovery dload fastboot etc.

Hi. Sorry the revive.
Could you solve this? I'm in the same situation
No unlock, can't enter to recovery, can't enter to erecovery so I can't flash with dload, fastboot is a joke if the phone has locked bootloader so I can't reflash the recoveries.

Hi everyone!
First, sorry reviving the threadm but this one is similar to my trouble.
Second, every flash process was done with dload method and vol + - and power combination.
Third, I never unlock my phone before or flashed any custom rom or recovery, everything was stock.
Last night, I tried to rollback my honor 8 frd-al19 to emui 6.0 with proper rollback package and firmware for Android 6.0 (both official and for my model), but phone went into boot lock. It isn't boot loop, It's stuck on the Honor blue logo. I can't even turn off the phone.
I did this procedure once before with success. I was on fdr-al19c432b360 firmware 100% functional (I was an idiot to rollback again when not needed at all... I know). I applied the rollback package correctly, and then I did a mistake and flashed full c636b131 Android 6.0 firmware instead of c432b131 Android 6.0.
Phone started ok with everything working. But I noticed my bad (emui didn't find any update package from OTA, and noticed the error in version model shown) and reflashed rollback package... At this point is where I think I messed up the recoveries or something. When ended the flashing process, I copied the correct firmware (the c432b131 android 6) on dload folder and tried again to flash.... but this time phone never entered on erecovery nor recovery. Only thing I get is stuck honor blue screen. It refuses to enter on recovery or erecovery. It just reboots, vibrate twice and keeps stuck after that on honor screen.
Strange thing, is that I did this procedure once before some months ago with success, but that time I didn't make the mistake with the versions.
After panic, I tried to boot in fastboot connected to my pc, and HiSuite knows there is something connected, because it launches it self, but don't recognize the phone and says it can't be recovered. Also, Adb don't see the phone either, only fastboot.
With fastboot commands I tried to reboot into recovery and nothing happened. Then wipe cache/user data, reflash stock recovery. Everything failed with message "remote: not allowed". And of course, because I never unlocked my bootloader. Fastboot says phone locked, frp locked (was frp, don't remember now exactly).
Then, I read about to let the battery die. I did. That didn't work either, phone keeps stuck on honor blue logo.
I downloaded multitool for huawei software, and everything requires an unlocked bootloader to recover.
Then, I tried to get unlock code, but huawei site ask me product id which I can't get because phone is bricked (I have all other data, imei, serial, etc.) . Tried with id generator too, and nothing what I tried have work so far. It's frustrating.
I'm pretty hopeless now, no unlock, no recovery, no erecovery, so I can't flash anything on the damn phone to try to recover it.
Can I save my phone or is it just an expensive brick? Any help will be REALLY welcome.

Well, is a bit silly to answer yourself but this can help someone else:
I did purchase a license of 3 days of dc phoenix software and force updated version android 6.0 c432B131 on my honor 8 fdr L19.
It flashed ok, but software said that couldn't install update. On phone went to 99% for long time (more than 1 hour).
So I looking for some info, and also the software said that I had to manually update. I just copied the same rom with dload method: just the same UPDATE.APP on the folder, and tried the 3 buttons: It worked!
After a success bootup, it found inmediatelly (OTA) the update to android 7, c432b360 firmware and downloaded and installed.
Here went something strange: after updated again via OTA, everything was working ok, but on about phone, the version shown wasn't the c432b360. Instead it said something about test keys build. Just for being safe, I tried to full reset the phone and... it failed. It said failed on erecovery menu, and after that, the next boot up I couldn't pass over wifi setting menu: keyboard was missing and it just tried to talk to text input. Another panic moment, so I tried to enter on recovery to clear cache and reset user with no luck. After that, phone refused to start showing an error message on fastboot screen: "phone couldn't pass verification, it may not function properly".
What to do? just do all the things again, but just with dload method. As I was on android 7, first I installed downgrade package. Ok, it did well. After, installed again c432b131 (android 6). And finally success!.
Once again, phone ask for install OTA android 7 and I let it. Now, I just didn't tried to do a factory reset and so far is ok.... but it hasn't AOSP Android keyboard anymore. So far is working ok, everything is working: wifi, phone, 4g mobile internet, nfc, sensors, apps, gps, compass... so I'm pretty happy now, but not sure what happened when I tried to factory reset and what happened to AOSP Android keyboard.

A late answer but maybe useful for some
Because the OTA showed up, was not a full OTA file. I guess it was only 1.3 gb something. It was a test build and didnt have any apks inside including the keyboard. And also not a stable one (test build) So it is always better to download FULL package from the menu and flash that one.

[Q] Bricked TF700 when trying to install TWRP

Current Status of my TF700:
-Boot looping with Asus "Inspiring Innovation - Persisten Perfection" logo. Approximately 5 seconds between reboots, with a vibrate every time it reboots.
-It says "Device is Unlocked" in the top left.
-Holding power for a long time (over 20s) will shut it off, and vibrate, but then it immediately vibrates again and resumes the bootloop.
-I cannot get it into the bootloader with Power + Vol Down. That combination does nothing.
-If I use the pinhole button, as long as I hold it, the screen remains blank. As soon as I release it again, the bootloop resumes immediately.
-It does not get to the second "shiny" Asus logo.
-It doesn't get far enough to recognize a new firmware file on the microSD card.
How I got to this point:
Stock ever since I bought it up until a few days ago. I decided it was time to root, unlock, install TWRP, and install CWM. I never got that far.
1. I unlocked first. I believe it was successful because it has said "Device is Unlocked" ever since.
2. I tried to root with the debugfs method. It reported it was successful, but despite several attempts, it was unsuccessful.
3. I tried using GooManager to install TWRP. It never worked.
4. I discovered that I wasn't running the latest Asus firmware. I then upgraded it. It ran successfully. (V10.6.1.14.10)
5. I tried rooting with Motochopper. It reported success. But it didn't work. I then discovered it wouldn't work with V10.6.1.14.10.
6. I then tried installing TWRP via fastboot. It reported success, but Power+VolDown didn't get me into TWRP. Nothing seemed to load TWRP. In case it's relevant, I was having trouble where Windows was saying there was a problem with the Bootloader Interface Driver, and after several reboots, I was able to get fastboot to reportedly load TWRP. It reported success, but I never saw TWRP.
7. I booted into Recovery, the latest version that said something to the effect of, "USB recovery loaded" or something, with 3 icons: RCK, Android, and Wipe Data. This is the only recovery I was ever able to see, by the way. I then selected "Wipe Data" hoping it would give me a new starting point.
Once it rebooted, it has been stuck in this bootloop. Have I royally screwed myself, or is there a way to recover?
Please ask any questions, I will answer them to the best of my ability. In the meantime, I will hope to run the power down on the tablet in the hopes it will make a difference.

Power+VolDown activates the bootloader menu - this is the screen with the 3 icons, where you can use fastboot. Since you needed to go there to install TWRP via fastboot, you should have known that Power+VolDown doesn't get you into TWRP - you'd have to press VolUp in the bootloader menu, to activate RCK.

Selecting "Wipe data" from the bootloader menu with a broken recovery is the best known way to brick a TF700. This can only be recovered via nvflash, which you can't use since you never got far enough to extract the required files from your tablet while it still worked. Your only option now is a new mainboard.
Well, crap. RCK never did anything except show a loading bar then reboot.
Thanks for the reply.
...from my phone...
Anyone know of a place that sells 64gb mainboards? Not finding anything thus far...
...from my phone...
in case anyone cares, I swapped the motherboard out with one from ebay, and it booted right up.

Problem with devices stuck at eRecovery after update to B360

Hi guys.
Im hoping someone has a clever fix to my problem.
Version: FLD-L09C432B131, rooted and with TWRP.
Issue:
I took a plunge into the updating sea and installed B360. Never thought it would go through since I didnt unroot first. Well, it actually worked and the phone booted fine. The "About" part listed the new version but I was still on decembers security patch. So I ran Firmware Finder and started with the small file, 230MB or something. Unpacked it and moved to dload via the menu in FF.
Now the problems began. Phone booted and ran the update without any noticable issue....until it was time for a reboot.
It now only boots into Huawei eRecovery with the options to:
"Download latest version and recovery" - Which fails after connecting to wifi and trying to download from huawei.
"Reboot" - Just returns to eRecovery.
"Shutdown" - self-explanatory.
The devices does show up for a few seconds in ADB when it reboots and is connected to my PC. But not for long.
I was hoping to be able to flash TWRP with ADB but its kinda hard when it doesnt stay connected.
Anyone wise out there with some input?
Much obliged.
/nort
Ok update.
I managed to get adb to work finally by timing the seconds the phone was actually visible to the computer. A reset back to B131 and now im on B360. Not sure if i have the latest version with the battery fix but I guess that will be obvious soon enough.

Bricked. No recovery or fastboot

Hey,
I need some help with this problem. I have a frd lo4 on nougat. I tried to return to stock from being rooted. The dLoad folder method wasn’t working (returned invalid package) so I unrooted via the SU app, flashed stock recovery, and went into fastboot and relocked the bootloader with the code.
Now it won’t boot or shut off. Just a bootloop showing the blue screen. I could use to access fastboot before but now my pc doesn’t detect my phone. I’ve tried different ports and pc’s. I can’t access recovery either.
Any help is appreciated
EDIT: I let the battery die, then tried going into fastboot mode and it worked. I flashed the stock recovery 1 and 2. I then used the correct rollback package and put it on my sd card then flashed. I then downloaded the full 6.0 firmware and did the same. Now I’m unrooted, locked bootloader, and stock.
Hope this helps someone.
Excatly the same thing happened to me 1 week ago.. My phone was going on bott loop in recovery mode.. I tried Dload method and recovery but nothing happened.. atlast i let the battery die. After the battery is completly dead i connexted the charger and hola the adb is working now. Then i flashed correct recovery and rom. Ecerything is working fine now.

Honor 8: unlocked bootloader, no OS, no recovery, no adb, no fastboot

Hello,
I had FRD-L02 stock with EMUI 4. I bought phone on Amazon in USA. It was working there and I haven't had any problems in Europe too. But then one day came and the phone was stuck in boot mode (those 3d honor letters). Nothing helped except factory reset. I did it and phone was working fine for half a day or just one day. After that the same scenario was repeating and I was doing factory resets.
I was not able to see any updates. Dload was not working.
I bought a bootloader unlocking code from DC-unlocker. It worked. Then I used fastboot mode to flash TWRP. After that I used HWOTA8.
I tried to install FullOTA-MF-PV package with FRD-L09C432B521 (8.0.0.521) (update_full_FRD-L09_hw_eu.zip ; update.zip ; update_data_full_public.zip ). So I was not only updating OS but I was also changing the region. During the installing moment of the second package I accidentally touch the screen and installation stop (maybe it would be happening without touching too). After that the bootloader screen changed. I had EMUI 8 and it was working fine except it didn't had keyboard and a lot of apps. It seems that I have tried everything to install fully all of the packages. I had some problems in the way but then I succesfully load fastboot, installed TWRP once again (actually, I couple different ones; some of them was not giving full access to the files). So I was able to load HWOTA8 once again. It seems to be working fine... But after that I am stuck with unlocked bootloader with no OS, no recovery, no adb or fastboot, no sound when connecting to PC.
Please, could you help me? Is there any way to fix my phone?

The problem is that I can't start fastboot mode
Actually, it is possible to go to fastboot mode. Just wait till the battery is empty, then press volume down and then connect to pc.

Galaxy S7 G930U Unlocked stuck in boot loop - already flashed successfully but no fix

I'm really hoping you guys can help me out here. This is an S7 I bought from a Best Buy when I visited the US in 2017, and I got the Unlocked version so I would be able to use it back in my home country. Unfortunately, this is the second time I've had trouble with it in a span of 4 months and the first time it was a hardware problem and ended up quite expensive to get fixed.
Today I was using my phone normally when I decided to use the Google instant translation to translate something on my computer screen. That caused my phone to freeze, restart, and then tell me I was using an unauthorized flash and it was going to be locked, or something like that. Even after restarting a few more times, the phone would never get past that screen. I proceeded to factory reset/cache reset and from then on the phone just got stuck in a boot loop.
I learned that the fix would be to flash the phone. After a lot of work I found the G930UUESACSI1-20190930144640 firmware (the XAA version, for Unlocked) and successfully used Odin 3.13 at the Download Mode screen to flash my phone. It then restarted, went back to the blue screen, started installing some updates, when it was 100% it restarted again. Unfortunately, the loop remained. Galaxy S7 logo first, then the Samsung logo, then it just repeats.
I have also tried turning the phone off with the Recovery screen shut down option (since I can't seem to be able to turn it off with the power button right now), wait a few minutes, then turn it back on. Nothing changed.
Please, does anyone have any insight into this? What else could I possibly try, or what could I be doing wrong? I really don't want to send it to repair yet again in such a short time.
Many thanks in advance.

I'm really hoping you guys can help me out here. This is an S7 I bought from a Best Buy when I visited the US in 2017, and I got the Unlocked version so I would be able to use it back in my home country. Unfortunately, this is the second time I've had trouble with it in a span of 4 months and the first time it was a hardware problem and ended up quite expensive to get fixed.
Today I was using my phone normally when I decided to use the Google instant translation to translate something on my computer screen. That caused my phone to freeze, restart, and then tell me I was using an unauthorized flash and it was going to be locked, or something like that. Even after restarting a few more times, the phone would never get past that screen. I proceeded to factory reset/cache reset and from then on the phone just got stuck in a boot loop.
I learned that the fix would be to flash the phone. After a lot of work I found the G930UUESACSI1-20190930144640 firmware (the XAA version, for Unlocked) and successfully used Odin 3.13 at the Download Mode screen to flash my phone. It then restarted, went back to the blue screen, started installing some updates, when it was 100% it restarted again. Unfortunately, the loop remained. Galaxy S7 logo first, then the Samsung logo, then it just repeats.

You need to clear the cache after flashing to get out of the boot loop.
Use the download key combo to restart. As soon as the screen goes black move to Volume up+home+power.
In the recovery menu choose clear/ Wipe cache, then choose reboot.
I apologize for not updating this thread before when it was still recent. The fact is that I didn't manage to fix my phone; clearing the cache after flashing did nothing to stop the loop.
I ended up taking the phone to the people who have fixed it in the past and after more than one month, they gave up. So I got my phone back and I want to try to give it another go before I just sell it for parts.
Unfortunately, my phone has come back even worse. Now it has no Recovery Menu to speak of, at least none that I can access; after a few seconds of the blue text on the top saying that it's entering recovery mode, it then proceeds to a blue screen saying: "Security Error: This phone has been flashed with unauthorized software and is locked.". I can still access Download Mode.
I have attempted flashing a few firmwares that I believe should have worked with my SM-G930U. Odin listed the attempts as "pass" and, after restarting and going back to the Download screen, it says the binary is Official. However, after trying to restart the phone normally, it starts displaying the blue screen again, and then, after going to Download mode, the binary is reverted to "Custom".
I believe right now the order of the day is to get the recovery menu to work again so I can do all the cache cleaning that seems to be required after flashing firmware. Any ideas at all on how I should proceed? Is there something specific I should download to fix the recovery menu?
How many files are you flashing in Odin, is it just 1 file in the AP slot, or 4 files: AP, BL, etc.? Also, is your phone rooted?

Never rooted, was using the phone legit before it froze and entered boot loop. I flashed all 4 files, multiple times.
Someone tried fixing my phone a few days after I replied to this thread and some progress seems to have been made, but now the phone cannot get past a black screen with a "SBL Error! rdx_init!" in red text, and "upload mode" in yellow text. Still cannot access Recovery Mode, but Download Mode still works.
I did a little Googling on rdx_init errors and it seems I need a firmware dump from another G930U or something like that...any ideas on how I can proceed?
Flash it with Eng Boot in all slots using patched Odin. Reboot to recovery and wipe it. Reboot system. Then root it with advanced adb root. Links for all of this are here in xda. Enjoy

Sorry, I'm not an expert at this by any means, I'm not sure what files to get. So far I've found and downloaded the following:
S7_Oreo_Nougat_Adb_Advanced_Root_V10
S7_Oreo_Nougat_Adb_Advanced_Root_V12
S7_Oreo_Su_Binary_Only_ADB_Root
But I had no luck flashing any of these cause my binary is 10. Is there any more help you can provide me? I really don't know how to proceed

I thought I had one in my phone, but I don't. If you look at the thread where you downloaded the Root_V12, you will see it. It's near the end of the thread somewhere.
