Mate 7 - No recovery possible + battery problem - Ascend Mate 7 Q&A, Help & Troubleshooting

Hello everyone,
I know there are a lot of post with similar problems, but ive tried them all and didn't succeed.
My problem is that i installed the kangvip rom (5.1.1) and then upgraded to the new b510 mm rom via http://forum.xda-developers.com/mate-7/development/update-to-b510-mm-kangvip-b354-v2a-mate-t3287804 this guide. But the installation got stuck on 5% so i rebooted it. Since then i flashed a few roms via fastboot and now i dont know what rom/android version i'm in. Also i can't boot to recovery (with 3 button trick) in any way. Lastly my phone now says that my battery must be charged while i had in on plug for the entire night.
I hope someone has a hint or solution for this.
I have a MT-L09 European version.

H60-L02 return to stock help

Hey guys,
Have had my Honor 6 H60-L02 FDD-LTE for little under 4 hours now
Already unlocked the bootloader and flashed CWM V.6.0.5.1
I installed the MIUI v4.9.6 Rom and i don't really like it, it keeps coming up saying com.android.phone has stopped, and when you update to v4.12 it gets stuck in a boot loop
So I don't think MIUI is very stable for the phone, and I want to install EMUI v3.0 (This isn't lollipop yet is it?)
Long story short, I figure i have to reflash the stock recovery firmware because CWM wont install an Update.App file
I downloaded the Honor 6 Multitool
When i get to install recovery, i choose my honor 6 model then it asks for EMUI 2.3 or 3.0, i tried all the 3.0's and they dont load the recovery, just go back into android
so i tried some of the EMUI 2.3's, i have no idea what each number at the end represent and which one suits my phone... i.e B118SP02?
So that is what stage im at, i have MIUI v4.9.6 with CWM V.6.0.5.1
And i am trying to install EMUI v3.0 stable
Any help would be pretty awesome, can say im slightly disappointed with the availability of roms for this phone, but hopefully this will change in the future
Ok ...
i will start from beginning , i will tell you how to get the last stable update for your phone .
witch is B310【EMUI3.0_Android4.4】.
First Download it from here it's 1GB .
or from here (you should translate it first and click on stable and download) .
Second continue with this link .
Attention : Do step 6 before 5 .
Or go to
http://forum.xda-developers.com/showpost.php?p=57274153&postcount=1
scroll down to: 3 Button Restore not working (If you change between variant example L02>L12) Or Partition been changes and cannot restore back Stock version. Use this steps below : -
Links to the revert package etc are in the post too
Tried Myahyam's method and now the phone is stuck in a boot loop (shows the honor, powered by android splash, goes black then repeats the splash)
need to unbrick the damn thing now
im following the honor 6 multitools unbrick method, its in fastboot transfering files now, will report back when its done.
Just out of curiosity, besides MIUI and EMUI, what other roms are available to flash using CWM or TWRP?
Okay, managed to get CWM back on and sideload the MIUI4 rom again, just to prove to myself that I didn't brick my phone, so that parts all good!
I will have to try your method another time Julsen, i fly out on a 3 week holiday tomorrow morning, and want to load some games and movies to the phone to watch on the plane.
Hopefully when I come back in 3 weeks, there will be a better choice of roms to install using CWM/TWRK
If not, I will attempt your method Julsen, at least i now know how to fix any softboot/bootloop problems, good learning experience all up!
Here u will find couple of custom roms flashable via cwm

Hey all, back from my 3 week trip
@nrpetonr i went to that site and grabbed two roms to flash using CWM, they both seem to put it into a boot loop
This phone is strange really, ever since i have unlocked the bootloader and put on a custom rom, its been the only rom that has worked, the rest all put me into a bootloop
Maybe i should try TWRP instead

Restart loop

Hello
I use a ROM with XT897 CM10.2.1 and SIM MOD CornholioGSM since July 2014, it was working fine.
I flashed the ROM-cm-SNAPSHOT-YOG4PAO23E 12.1-20150901-xt897 (RELEASE) one month ago and the ROM worked well. A week ago, the phone was much slower, I turn off reboot and since it constantly!
I made the following transactions with TWRP:
- Reset factory
- Flash ROM (cm 12.1-20150901-SNAPSHOT-YOG4PAO23E-xt897)
- Flash ROM (BlissPop-v4.0.1-xt897-OFFICIAL-20150917-1514)
- Flash recovery (cm 12.1-20150901-SNAPSHOT-YOG4PAO23E-xt897-recovery.img)
- Flash TWRP
- Flash ROM (cm 12.1-20151007-SNAPSHOT-YOG4PAO339-xt897)
Always the same, I have the boot logo and the logo of the ROM and the phone reboots.
The ROM (CM12.1) has started once and then restart the phone has rebooted repeatedly.
I tried with or without a SIM card.
I do not understand where does the problem, can you help me?
Well not having the phone in front of me, I don't really quite understand the issue myself - however, I would suggest using RSD Lite and one of the FXZ files to flash everything (including recovery) back to stock.
If you still have issues, there is a bigger problem (likely hardware failure).
Hello
sorry if my explanation was not clear.
I added a photo which shows the two steps in the operation of my phone.
Step 1: Start the phone .
Step 2 : boot ROM CM12
The Step 2 lasts 23 seconds then return to Step 1 and Step 2 and Step 1, Step 2 infinitely .
I hope this is understandable .
I read on the forum that used some RSD Lite but as I had not used for the ROM installation, I did not understand why use .
I'm a new user, i can't post picture, I send link by PM, thanks.
I thought my last post made it clear what purpose RSD Lite and the FXZ files are - they restore the phone to stock completely - ROM, recovery, everything will be reset to when it was stock from the factory (granted it may be a newer image than what shipped on the phone, but you get the point).
Again, as I stated previously, if you still have issues after flashing everything stock your issue is likely not software, but hardware.
I searched the forum about RSD Lite. Now I understand its usefulness.
I used RSD Lite to flash the ROM asanti_c_sprint-user-4.1.2-9.8.2Q-122_XT897_FFW-5-6-release-keys-cid9.xml.zip
My phone had with SPRINT .
The flash went well but unfortunately I still have the same problem :
Step 1: unlocked bootloader screen
Step 2: The red M MOTOROLA
Step 1, Step 2 , .....
Is there another test or I can consider it a hardware problem ?
Hardware problem can come out of the MODSIM ? I use a SIM card in the phone for 16 months.

The hardware issue is likely not related to the SIM modification. As to what exactly has failed, I'm not sure... perhaps the NAND or something else memory related.
Aouch aouch...
Thank you for your help.
I think it remains for me to search for a motherboard for photon Q.
Long life in the forum!
Use "borrowed" TWRP recovery image.

I had a similar incident a few days ago. I have a hard time stopping myself from pushing the limits. Usually I stop when it's broken. I tried RSD Lite, SDB sideload/ flash, zip install from recovery, fastboot(mine's dead), all with no luck.
Any how, If you have CWM, temporarily change to TWRP. If you already have TWRP it's easier.
XDA has a TWRP recovery image in the forum. Put that in your sdcard (I had to paste it from my computer because my xt897 was soft bricked). Flash from TWRP.
Worked fom me. got my phone back after 1 week of flashing everything and then some.
Good luck.

Hello
thank you for this new information.
I tried it and it worked with the ROM [PQ_ICS-Stock] but only with that one!
I tried the ROM [PQ_JB-421] , several Cyanogen ROM but still the same looping boot problem.
I tried several version of TRWP without success .
I do not understand why my Photon Q only works with this ROM [PQ_ICS-Stock] .
Is still a motherboard problem ?
Hello everyone
I'm going crazy !
As I had not managed to solve my problem, I ordered a mainboard on ebay.
Today I realized the SIMMOD on this new board.
when I restarted phone the same startup problems with the ROM SPRINT !
I unlocked the bootloader .
I installed TWRP 2.7.1.2
I installed CM12.1-20151219 - NIGHTLY - XT897
Still the same problem starting loop.
Someone an idea ?

If you can't RSD Lite, something is up. Either you are not doing the process correctly, or there is something wrong with the device (still).
Perhaps you were always on ICS and never made the official jump to JB? You say you can RSD Lite to an ICS version, just not a JB version? So 4.0.x works but 4.1.x does not?
Again I'm talking stock. If stock doesn't work, I wouldn't even attempt CM. Start with the basics, then work your way towards the aftermarket.
I agree that if the stock rom does not work after the installation with RSD Lite is that it remains something (software) .
The first motherboard I used 12.1 CM for several months it is that the phone supports android 5.1
I agree that it must abort running a stock ROM before flashing a ROM CM. But the ICS ROM STOCK works!
It is possible that I did not do the process correctly .
What surprises me is that the second board had the same problem with the ROM SPRINT !
I will do other tests.

This is the part that makes me think you are perhaps missing some step in the process somewhere.
Can you RSD Lite to ICS? Not flash it with TWRP. If that is successful, try to RSD Lite to the latest JB again.
I modified the second motherboard ( mod sim card ) and I started the phone with the ROM SPRINT and I got the boot problem repeatedly.
the common point of two motherboards is that they both have a bad ESN .
I will do other tests.

Bad ESN shouldn't prevent booting... it would prevent you from activating the device on the Sprint network, but I would imagine you don't care about that...

I used RSD Lite 6.1.6 for flashing the ROM [ 2014-03-09 - TSv2 ] but the process has blocked after the flash.
Here is what I did :
1- run RSD Lite
2- Start the phone in FASTBOOT mode.
3- usb phone connection to PC
4- opening of the ROM [ 2014-03-09 - TSv2 ] and "uncompress and start flashing"
5- flash goes well
6- the phone reboots => Logo M red => telephone reboot => Logo M red => again ....
7- RSD Lite waits for the restart ... [ it waits again, LOL ]
8- I turned off the phone and I unplugged.
9- I turned on the phone who start properly, I arrived at the language selection screen .
The ROM is an android version 4.0.4 , I think you know this ROM .
Why the process with RSD Lite has blocked the phone to reboot ?
That's what I did wrong in the process?
I have read many forum post, I tried several methods but only in the ROM 4.0.4 STOCK work. Flashed with RSD lite or restoration of a backup with TWRP.
I have the bootloop problem using RSD Lite 6.2.4 for ROM 4.1.2 CSPIRE or ROM 4.1.2 SPRINT. No error message of RSD lite. No error message of phone.
I've modified the XML file but it changed nothing.
Same problem using TRWP with custom ROM or restoration of a backup ROM4.1.2 JB.
Same problem using OPEN RECOVERY 209 with custom ROM.
Where is the problem ?
I would use CM12 ROM.

Without having the device in my hands, it's hard to say for sure. The only difference I can see you are doing differently from me is using a newer version of RSD. I doubt that would be an issue, but may want to try other RSD versions.
In the end, I suppose if 4.0.4 works, use that...
Thank you for you help.
I'll buy a other PHOTON Q on EBAY.
I do other test with the new PHOTON Q.
Hello
I received my new q photon.
It is version 4.1.2
I unlocked the bootloader .
I made a backup with TWRP and OPEN_RECOVERY_209 .
I tried an installation of 3 different ROM but I have an error message !

Is this a bad version of TWRP or ROM ?

Shield Tablet LTE stuck at Bootmenue/Bootloop

Hey Folks,
got some messy Prob's with my old nVidia Shield LTE Tablet.
The Facts:
-KillSwitch not Triggered and it was succesfully Rooted in November 2015, TEGRA-OTA was also Removed (nomoreota)
-worked for Months (beneath one year), only Super-SU penetrated me periodely that it needs to be Updated, but it couldnt be done, it said "not enough Space" after trying to install a newer Version. :silly:
-past Month (January 2017) i decided to do a Factory-Reset, because Girlfriend should get the Shield, thats where the Problem started:
After clicking Factory-Reset, it began to work. After 4 Hours and nothing happening, i decided to Power it Off and start fresh with Installing a clean Stock-ROM and remove the TEGRA-OTA as i done a year before.
But from now on things get messy and to complicated for me.
In the Past i rooted and flashed it with "Shield-RAM", found here on xda.
But this Time it didnt ended with a working Shielt-Tablet. It stucks alwas in a Bootloop, in Recoverymode also as in normally booting the flashed OS.
Confused an disturbed by this, i tried different Recoverys (TWRP 2.8 and 3.0, also a CWM), all with the same Effect: Bootloop
Now i only can acces the Bootmenue which says Bootloader Unlocked.
I dont now what to do from here on and would be very happy and glad, if someone can help me figuring out whats going wrong.
If further Details are needed i will do my best to provide things i forgot here to mention.
With kind regards - ToxicFighter1
Ps.: excusy my bad spelling, bit rusty in flawless english typing:good:
Hi !
There is this thread where you can try to get it back to stock https://forum.xda-developers.com/shield-tablet/general/unofficial-update-original-shield-t3281541
This nice index may help as well
Good luck !
Thanks, but that's not the problem. If I boot into Fastboot / Bootloader, it's totally fine. In fact, I can plug the tablet up to my PC when it's in any state and doesn't experience the issue. It only occurs when I have it plugged into AC. SO far, I've tried 3-4 different cables and power supplies for 2.4A, 2.1A, and 1.2A - all adapters which worked 100% prior to updating.
Suggestions?
OK - Finally fixed it...
I replaced everything as shown above, but ran into the issue again as soon as FlashFire installed the OTA. So, I tried a different way to upgrade and no longer have the issue. Below is what I did...
- Installed 4.4.0 via ADB/fastboot wirhOEM recovery
- Completed initial setup and upgraded to 5.0 via built in system update
- Rebooted
- Booted to bootloader and flashed TWRP recovery
- Booted to TWRP
- Installed SuperSU via sideload
I would have started out applying 5.0 via adb/fastboot, but have yet to see a full image available yet. Used same TWRP and SuperSU as originally used. Just eliminated GlashFire from process. Once I rebooted and everything loaded, plugged into 2.4a power, and it worked without going into boot loop.
Hope this may help someone else - Thanks
Hey Folks,
thx for the few answers, i'll try these Tips out the upcomig Days.
Lot'a Stuff to do atm, bit Busy.

After Flashing half blue screen

So guys, I installade on my Chinese Version le 1s an India Version via SP-Flash.
So after flashing half of the screen got blue, my dad told me its because those roms and the version dont get together along.
I cant go to fastboat mode, only recevory or normal booting.
I´d like to have a Chinese Rom, that I can flash via SP Flash tool.
I cant go on the original chinese site cuz I cant connect there.
Pls help me Im new to flashing
did you find how to fix it.
half blue screen issue
Yesterday, I had also had the same issue. This is due to incompatible rom. In my case, the flashed rom was 5.5.014_Le_X509_Stock_Rom. So, after hours of struggle finally, I solve the issue. Now my phone is working fine. May be my experience will help you.
Following are my steps to solve the problem:
1. Download the Eui 5.8 019s offline update ROM(please make sure it is official and compatible with your phone).
2. Add ROM to internal storage.
3. Rename ROM to update.zip
4. Now power off phone and go to recovery(power+vol up)
5. Clear cache
6. Update ROM.
7. Device might take some time to boot. But the problem will be fixed.

[Please help!] Unable to root Samsung S7 8.0

So first off I would say I am average in the world of modifications, I know the basics. I used to run a stock Nougat rom with Magisk.
Being the clumsy fool that I am, I dropped my phone and the screen broke. I went to a Samsung service center and deposited my phone there for screen replacement and they decided to update my phone for no reason...
As my phone was rooted, after forcing an update on my phone a soft brick happened and they had to flash a new firmware which meant that I lost everything. Now I am running latest stock Oreo 8.0.
I tried these things to root my phone again:
(The first thing I did was flashing twrp through odin)
#1: Downloaded Magisk and a decryptor for getting past the locked bootloader... flashed them both using recovery (twrp works 100%), and my phone got stuck on the Samsung S7 - powered by android after a reboot from recovery. Waited for a long time. Tried a lot of alternatives on this method but got stuck..
#2 After I gave up on rooting the firmware I was given, I decided to go back on my old Nougat firmware which used to work flawlessly... so I had the nougat firmware on my computer but this time Odin gave me an error along with some red text on top right in download mode. I looked up the error and it basically meant that I cannot revert back to Nougat anymore (which is surprising as I could easily swap between Nougat and Marshmallow but I can't do the same with Oreo and Nougat)
Quote from a person on the internet: ''SW REV CK FAIL usually means that you are not flashing the most current released firmware version. Most Samsung devices will not let you downgrade. You have to flash what was previously installed or higher Android version.''
#3 I was frustrated. I tried using a last resort.. downloaded a custom rom which has root included called ''Galaxy Project''... Flashed it using twrp and got a bootloop for 2 hours. To get past the bootloop I had to download Oreo stock rom and flashed it using Odin. That worked.. I'm back on stock Oreo again... back to square one.
Please help out a stumped Android enthusiast... I have spent 2 days on this... but no solution works. My phone is not in danger of a hard brick as I can always revert to stock Oreo using Odin but having root would be nice.
I am having average experience, I know just the basics... please help me out and tell me what to do in a step by step manner.. I will try everything and report the findings till I finally come across a method which works.
EDIT: My phone model is G930FD
